Vandervell has made bearings with different characteristics over the years. The two materials you will find today carry the Vandervell designation VP2 or VP19. VP2 is the material most people are looking for, this is also known as the ‘tri-metal’ bearing. The load carrying capacity of this bearing is around 7000 pounds per square inch. VP19 material, known as aluminum tin, is used by most car manufacturers in new cars VP19 has a load bearing capacity of about 4500 pounds per square inch. These bearings in our list have “A” after the part number. It’s a sad fact, but in the near future at least, it looks like only the “A” bearings will be available in some cases.

948 main bearings, VPM592, are few and far between, al-though we do have some sizes. You may be forced to use VPM733 for this application. The bearings are narrower, but work just fine in practice.

Running a “Dingle Ball Hone” through the cam bearing bores before fitting new cam bearings is always a good idea.

Small end bushes are NOT pre-sized. They will need to be reamed and/or honed to size after installation.

A well-built bottom end is the foundation for any build. When we build an engine it gets a thorough cleaning with the galley plugs removed, line bored, the rods resized, and all holes re-tapped and champhered. It can take almost countless hours to do it right!

With enough patients and offset keys you should be able to get the cam timing spot-on. Keys are available in 2, 4, 6, & 8 degrees.

This timing pointer is easy to make and easy to see. You can mark your spot while you’re doing your build and not have to trust the factory marks!

Always use new cam followers/lifters when installing a new cam. THIS IS VERY IMPORTANT!!

Titan roller rocker sets for: HLR-2 1275 A-Series HLR-7 Triumph 1500 HLR-5 MGB 1.625

We highly recommend that the timing chain tensioner on a ‘B’ series is replaced every time the engine has a major overhaul.

Use cam lube on all new cam and lifter assemblies. Just a smear on the lobe and lifter is all that is required. If you get too much of this stuff going round the engine it can get onto the cylinder walls and stop the rings bedding in properly.

Steel retainers are recommended over aluminum ones, which have been known to break. If you really want light weight, the Titanium retainers have to be the best.

Isky valve springs are known around the world for getting the job done. We stock them for A-Series, MGB, & Triumph

Too much we see today is manufactured to a cost rather than quality. For increased durability, we offer a line of nitrided rocker shafts for stan-dard rocker assemblies. A-Series, B-Series, and Spitfire are shown.

If fitting new stainless valves from APT in a “small bore” A Series engine you have to change to this type of keeper to suit the valve.

We can supply A-Series, B-Series, and Triumph cams ground on new blanks. Look for a part number that ends in “BK”. We nitride all of our re-ground cams.

Slacken off the 6 screws on Kent’s cam gear, move it a little, lock up the screws, recheck your cam timing, that’s it!

All hi-perf 1275 or bigger Mini should use #GCD-3 “orange” diaphragm. The # GDC-1 “Grey” diaphragm should only be used for race applications.

APT’s aluminum flywheels are made to accept standard discs and pressure plates, and come with the ring gear installed. (Except for TR3/TR4) Pressure plate bolts are included. We recommend ARP High-tensile strength flywheel bolts with hardened steel washers - never a lock-tab!

6-Cylinder Triumph cams are now available on new chilled-cast blanks. 1500cc Cams may be available by the time you read this!

CCP601-HD, for 1275, and CCP5 for MGB, are bonded and riveted to a solid, steel center. No springs atached!

Most ring gears we see on 30+ year old engines should really be changed during an engine rebuild.

All APT fully ported heads, road or race, are supplied with stainless valves, usually of the Rimflo design. They also have manganese bronze valve guides, springs and retainers to suit the cam being used. By knowing which pistons are being used we face the head to give compression required.

CCP2246 clutch cover for the MGB has a heavier spring so acts more quickly and posi-tively than the stock unit.

High Torque, Gear Reduction, Direct drive, call them what you will. These starters will crank ‘til you release the button. That can make the difference in starting vs. not at the “one-minute” signal.

Valve seat inserts are normally used for the exhaust only. The exhaust valve runs red hot, so the name of the game is to try and get the heat away from the valve seat as quickly as possible. These seats are made from a special material and do just that. We stock them for any application, cataloged by size. .

Rimflo valves feature special “anti-reversion” heads. We’ve tested them - they work! Made of 21 4N Forged Stainless Steel. One piece construction.

We also stock very high quality conventional racing valve. They are cut down on the back-side for improved flow. Made of 21 4N Forged Stainless Steel. One piece construction.

These are the manganese bronze Triumph guides. In a race head with 5/16” stem valves we sometimes use #FD16 which is machined for a teflon seal

A-Series Performance guides APT01A & APT02A have nice tapered ends. Seal # 5-07210 is known as a “positive type seal”. Take care fitting them, best to have the valve in the guide .

It’s hard to beat Carrillo rods if the budget and rules allow for them. We can also supply very high-quality rods from Pauter. Again, you sometimes have to wait a few weeks. The moral here? Plan ahead!

All APT Con Rods are mag’ed, lightened, balanced, resized, with ARP bolts installed. Please plan ahead, as with most of our services there is a wait time involved. RCR-6 shown.

It is simply a waste of power to run excessive oil pressure. With this stainless steel adjust-able relief valve assembly you can set the pressure right where you want it. This kit fits all A-Series, but will fit B-Series also if you swap springs. OPRV-ADJ

Wedging takes off only about 2 - 3 pounds, but dramatically improves the balance and hence the lifespan of an A or B-Series Crank. We also give special attention to the oil holes. We install thread-in re-strictors when appropriate.

The Friction Damper is the latest development for the A-Series. This one uses a standard v-belt and is a direct replacement for the stock pulley.

The gilmer belt drive kit for A-Series has an oversize pulley to slow down the water pump speed to stop cavitation of the pump on a race engine. The Cooper S damper #DAMP-S will bolt directly to the crank pulley.

COIL3 is Crane’s High Energy epoxy filled race coil. It’s suitable for all ignition systems.

Rover makes an 8mm wire set with 90 degree ends to fit top exit caps. If you have a side exit cap just snip off the ends– they’re then held in place by the screws..

Maniflow steel intake manifolds are typically worth 4-5 HP over the factory manifolds. S.U. manifolds have a small balance tube to maintain balance and easy adjustability.

For 1275s, 73.5mm bore gives 1380cc with a standard stroke. For road engines, P20950-00 is essentially the old Triumph piston, now made specifically for this application. For high-performance or race engines we recommend the “Mega” piston, P73-5, which is available in 7 or 11 cc dish.

AE’s “Mega” piston was made to fill the void left by Omega. They are a top-quality piston made to withstand high RPM & cylinder pressures. Features include a thick crown which may be machined for valve relief or to accommodate long strokes.

P21253 is AE’s “Cooper S” Piston. Compression ratio will be 9.75:1.

These are the 1900cc pistons for MGB, which is about +.080” We also supply 1927 & 1950cc sizes. We stock a special head gasket, too.

AFR-1 K&N air/fuel ratio moni-tor kit uses a row of LED lights to show if the A/F ratio is rich or lean. Its very simple, and if you don’t have access to a chassis dyno this is your best bet.

K&N’s pleated accordion design gives a large filtering area in relation to the filter size. K&N filters come pre-oiled, so cleaning and re-oiling is 20 to 50 thousand miles away

APT’s K&N filters are held to-gether with two through-studs, leaving plenty of room for in-stalling stub stacks. A stub stack is a very inexpensive $ per HP bolt on item. MSS2 Billet Stub Stacks are pictured.

K&N make dozens of crank case vents, but this one, part no. 62-1330, fits a 1/2” diame-ter stub so is most often used on British cars. Part numbers 62-1010, 62-1100 & 62-1140 have metal bases to fit into a 1/2” rubber hose.

Facet solid state fuel pumps have very few moving parts, so are a popular pump for all ap-plications.

K&N’s fuel filter is washable & reusable, just like their air fil-ters. It contains 6 sq/in. of filter material and will trap particles down to 10 microns. All with a flow rating of 15.3 GPM.

The object is to put a nice radius on the opening of the SU. Our Billet Stub Stacks do that, while fitting inside a 1-3/4” deep K&N filter.

For those of you who want to try something a little longer, or just plain like the looks, these Ram Pipes are reproductions of the Special Tuning ones. They’re made of steel, chrome plated, and feature a full radius. Available for 1-1/4” to 2” SUs.

CP-00 heat shield also holds the throttle and choke cable on single HIF6/HIF44 carb installations.

A Master rebuild kit includes all the parts pictured. A Service kit does not include the throttle shaft, bushes, or butterflies.

HIF44 has a larger top plastic filler to differentiate it from the earlier HIF6 type. The ram stack bolted to it is part # SSHIF-S.

We keep new S.U. carburetors and parts on the shelf, not just in the catalog.

APT stocks SU carb spacers for almost any occasion. MFA132, MFA388, & MFA448 have a vacuum takeoff that may be used for vacuum advance

HS type SU carbs use adaptors like this one to hold the float bowl at the correct angle to the main body. Midget & MGB use 20 degree, a Mini uses 30 degree, the 30 degree swapped front to rear gives zero degrees for Spitfire.

Carburetor notes:- Ram pipes for DCOE carbs slide into the main body and are held in place with the same special washer that also clamps the filter base plate. (Special washer part number PLATE004 or PLATE012). Ideally, clearance between the mouth of the ram pipe and the filter lid should be 1-1/2” or more. When selecting ram pipes the question of length is often answered by choosing a length based on available filter depth, however, in most cases, and unless you have a dyno to tell you other wise you might want to keep ram pipe length at no more than 20mm. Especially when using a long intake manifold (normally recommended) there can be severe disruption of fuel delivery if the ram pipe is also long. The most important function of a ram or stub stack is to form a radius entry for increased airflow. Longer ram pipes may be able to move the power points up or down slightly, but can also give major setup headaches! The operation of a DCOE can be split into three areas. Each of these areas must be addressed separately. The first thing to work on is the idle circuit. This has to be tuned first. Do not make the idle circuit rich just to cover a progression problem on the main circuit. The same line of thinking applies to the pump jet sizing. Also remember that the pump only works when you stomp hard on the gas pedal. If you have a hesitation when you squeeze the gas pedal slowly then this needs to be corrected in the main system. The emulsion tube only controls the shape of the fuel delivery curve, so there is always a combination of main and air corrector jet that will give the correct full power mixture. For siamese port engines we have found that a 5.0mm auxiliary venturi gives good results particularly for race engines.

One might consider a paved road course or oval track as a clean air zone. After all, how much dirt and debris could be hovering above an asphalt track? Subscribing to that theory, a road racer may elect to forgo an air filter in favor of large volumes of unrestricted air. However, testing the theory using an air filter enclosed in a vented housing should dispel the myth. The filter and housing will trap particles of loose trash kicked up by other race cars during the heat of battle. Dirt, small stones and pieces of shredded rubber expelled from soft compound racing tires can be found inside the housing after even a short race. Once a driver, car owner or engine builder realizes just how much trash is thrown around during a normal race, few would expose their expensive engines to unfiltered air in future events. Whenever possible, performance enthusiasts should install a K&N 360 degree open-element filter. A correctly sized conical or round filter will deliver 100 percent air flow with no measurable restriction. And, as we have learned, providing the engine with all of the air it needs promotes optimum performance. In a high speed application, a K&N filter will straighten the air which counteracts turbulence. Straight cut velocity stacks, for example, pose a unique problem. Exposed to the outside air, velocity stacks experience a phenomena that actually hinders performance at high speed. We are referring to stacks and air horns that protrude through the hood and extend into the air stream so the direction of the air rushing over the car is at a perpendicular angle to the length of the tube. Air moving rapidly over these stacks create turbulence inside the opening. At high speed, the rushing air tends to create a partial vacuum inside the tube. The condition is counterproductive to air flow. The phenomena also effects open carburetors. The higher the ground speed, the greater the problem. Vacuum created by the engine is trying to coax air into the cylinders and the high speed air flowing over the open end of the stack is causing resistance. Reversion creates other problems. In an automotive application, reversion refers to reversed air flow, or in simpler terms, it’s when air in the intake runner reverses direction for a split second. The condition is caused when a burst of pressure escapes into the intake runner from the cylinder during valve overlap. Studies have shown reversion creates resonance shock waves inside the tubes which exit the open end of the tube at various rates depending on engine speed. It has also been proven that these shock waves interfere with each other when the stacks are in close proximity. Installing a free-flowing air filter on top of each stack or over the carburetor air horn eliminates these conditions. How? The solution is simply explained. The filter creates a plenum over the opening. Air entering the filter is slowed, smoothed and straightened. The filter then becomes an endless source of calm, clean air. Shock waves dissipate within the confines of the plenum without interfering with the shock waves emitted from an adjacent stack.

K&N Filter Facts

1) Pleated wood pulp bonded together.

2) As dirt builds, passages are plugged and filter must be replaced in approximately 10,000 miles.

3) Irregular passages filter out dirt on a go/no go basis.

4) As fibers swell from moisture or oil blow-by vacuum pressure increases and airflow decreases.

5) Turbulent filtered air.

Conventional Disposable Paper Air Filter

Typical Foam Air Filter 1) Lack of surface area hinders air

flow and dirt holding capacity. Open cell foam usually saturated with oil.

2) Dirt builds on outside and blocks the openings.

3) Higher vacuum pressures distortthe cells drawing dirt deeper into the filter.

4) Airflow is reduced as cells become blocked.

5) Turbulent filtered air.

1) Turbulent air enters filter area. 2) Pleated multi-layered oil

impregnated surgical fabric 3) Suspended dirt on the outside

does not cause significant airflow restriction (up to 50,000 street miles)

4) Oil barrier attracts & holds dirt to become additional filter medium without clogging filter.

5) Bonded cotton/wire mesh straightens airflow, reducing turbulence.

6) Straightened and filtered high-volume air enters intake system.

Main Studs vs. Bolts ARP® recom-mends the use of main studs over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don’t “twist” into the block. All clamping forces are on one axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life. Finally, there are factors of easier engine assembly and proper alignment of caps every time. There are many important reasons to use ARP® main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. The studs are manufactured in our own factory using the best materials, processes, designs and engineering. Every ARP® main stud kit exceeds the most stringent aerospace specifications. ARP® uses a premium grade 8740 alloy that is rated far superior to “aircraft” quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 190,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality studs from other manufacturers who just dump pieces in a basket and hope for the best. Following heat-treat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It’s important to note that lesser quality studs are not even centerless ground—the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP® studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned—something that won’t happen with inferior quality head studs.

Tech Tips Rod bolts Unquestionably the most important fasteners in any engine are the connecting rod bolts, as they hold the key to the entire rotating assembly. A broken bolt will lead to catastrophic engine failure. As you can imagine, the most critical joint is where the connecting rod halves mate. The rod bolts must support the primary tension loads caused by each rotation (or cycle) of the crankshaft. When the crank rotates, the big end of the connecting rod essentially becomes oval-shaped and the rod bolts bend. As the crankshaft continues to rotate, the rod becomes round again. With alternating tension loads and cyclic bending of the bolts, it is very important to install fasteners that are able to exert a clamping force greater than the load imposed upon the joint (tension). In addition to utilizing a rod bolt with sufficient strength to withstand the tremendous cyclical strains placed upon it, it is absolutely imperative that the bolts be properly tightened. The preferred method of monitoring the correct amount of tension is through use of a stretch gauge. This is far more accurate than using a torque wrench. Moreover, through subsequently checking the rod bolt’s length at tear-downs, it is possible to determine if it has been stressed beyond safe limits and must be

Flywheel Bolts Flywheel and bolts play an important role in the performance and safety of race cars and street machines alike. That’s why the fastener experts at ARP® have developed special bolts that are far superior to OEM hardware . ARP® Flywheel bolts are forged from aerospace alloy and heat-treated prior to thread rolling and machining. Both feature an exclusive, flat, 12-point head design and larger than stock shank diameter for increased strength and improved flywheel register. The High Performance series is rated at 170,000 psi.

Ten things to consider 1. When you use a locking chemical for studs, bolts or even nuts, consider if you really need it. 2. If you are using a locking chemical, don’t force nuts off or studs out without a proper first step, like heat or release chemical. 3. If you can’t easily screw a nut and bolt together by hand they shouldn’t be used. 4. Consider the importance in regard to how many exposed threads are left when fastener is set. This has a bearing on necessary torque and ultimate strength of the fastener. 5. The best way to consider a fastener is as a spring of correct elasticity for that specific job. A fastener works best when stretched a specific amount. 6. If you can’t stretch the bolt enough, it can still fatigue, lose torque or get loose. 7. Use a stretch gauge whenever possible. This is the only fool-proof method of getting the correct clamping force. 8. Get access to a master gauge to check your torque wrenches. You’d be surprised at how many torque wrenches read incorrect. 9. Don’t forget that you’ll get different torque readings when using different lubricants. 10. Use ARP’s moly lube whenever possible.

Installing Main Studs in a Mini Block On 1275 engines the use of main studs gives a solid improvement over the stock bolts. But on the Mini there is something to look out for that doesn’t arise on an inline engine. Due to the proximity of the gear box webs at both ends, there is not enough clearance for the nuts. There are a couple of ways to deal with this: 1) is to leave out the washer and then sink the stud a little deeper in the block. 2) shorten the studs if you have a lathe available. The following photo’s should help show the steps to take.

Here, you can see how little room there is. All checking is done without gaskets between the flange faces.

First step is to remove the locating rings. The pliers shown are made to pull plug wires off spark plugs, but seem to work well for this application also! Tap all holes right to the bottom. Use the correct tap as shown, which, confusingly, is called ‘bottom’ or ‘plug’ depending on which country you are in!

On this block, this is how much the stud sticks out through the nut, and is being measured with calipers, (no washer) and needs to be shortened so it is flush with the top of the nut.

If you want to go the route of removing the top threads from the block you really need a drill press (pillar drill in England) or a vertical type mill. Use a 15/32” drill, and you MUST have a stop of some sort set up to control the depth accurately. (In actuality only the end mains need to be done.)

Here is the completed job. If you can see clearance, or can put a feeler gauge under the stud/nut then when the gasket is fitted there will be plenty of room.

Four areas shown painted white will need to be ground. The very best time to do this is obviously when the gearbox is stripped.

What’s wrong with the factory bolts? Factory bolts, at the very best, only have 65% of the clamping force of an ARP stud, and consider that the combination of the firing load and inertia at RPM cause loadings that amount to thousands of pounds. The last few foot pounds of torque applied to a bolt only twists it up like a torsion bar, and does nothing to increase the clamping load, not to mention possibly damaging the threads in the block. The factory use bolts because they are cheaper and quicker to assemble, so best engineering practice is always to replace a bolt with a stud whenever possible.

A-Series Main Stud Part Number recap… 850-1098 (small main) use #MSA44, 1098 large main & Cooper S use #MSA33, for all other 1275 use #MSA54, for the 2 extra studs for a steel centre main use #MCS-2, all have 12 point nuts & washers.

These instructions apply to APT Main Stud Kit part number MSA54 only page #33

(1) There is a technique to be followed if using lube rather than oil:- to distribute the lube between all metal surfaces the fastener must be torqued, then unscrewed, and the process repeated at least 3 times. You will notice that the torque wrench rotates a little further each time. When it doesn’t rotate any further you are done. (2) Fits all ‘A’ series, but can also be used on ‘B’ Series with Maniflow intake and exhaust manifolds. (3) Rocker studs, nuts & washers are included in these kits. Torque to 30 ft lbs oil, 20 ft lbs with ARP lube. When using some roller rockers you must check carefully and make sure that rockers clear 3/8” nuts/washers. Kit HSA11-B front 5/16” bolt torque 33 ft lbs with oil, 22 ft lbs with ARP lube (4) Cannot be used on the very low compression heads unless they are skimmed to 3.43” max. (5) Some early 1071 & 970 blocks used special bolts and these studs will not work without modifying the main caps (6)MSA54 – for a Mini only: do not fit the washers to the end studs on the mains, and also make sure the stud does not protrude above the nut. This may require drilling the top 2 or 3 threads out in the block (CAREFULLY) and perhaps shortening the stud also. Please see our web site for a complete step by step “How To”. The clearance on the gearbox casting must be checked carefully. In some cases it may be necessary to relieve the gearbox casing a little. (7) These studs will only work on a block that has studs already, bolt type blocks will not work with studs. (8) Check clearance on aluminum rail on end main caps, stud may need shortening or washer to be left off. (9) THS-1 stud kits suit housings up to 1” inch in height ALL ARP COMPONENTS are coated with an anti-rust coating, this is NOT oil and must be washed off before installing anything.

The MGB flow test shown to the right is interesting in as much as it shows such a huge increase in exhaust flow although the valve size has not changed. The port itself is more than big enough, but a big impediment to flow is the huge valve guide boss. The increase in flow below 0.300” lift can only be obtained by having a valve seat both on the head and on the valve (Rimflo) that is at the absolute optimum. The stock head we tested as a baseline was the very best we could find, it was a brand new late model factory casting. Most used heads’ flow figures would be lower. As most people are aware there is more to a successful performance head than just flow numbers. Keeping the port volume as small as possible while increasing flow is a major goal. The computerized flow bench we use calculates port velocity based on inputs from the operator of port volume and mean port length, this is just one of over 40 calculations performed at each lift point.

3 1/2" Long5" Long7" Long

Tested by David Anton & MikeParry May 1986 1400cc 45 DCOE Weber with 40mm chokes300 RPM per second test.

Maniflow produce 3 lengths of Weber intake manifold for the A-Series engine. Very often the choice of manifold is controlled by physical constraints. For example, on a Mini with a speedo fitted only the 3 ½” long manifold can be used, and this only after sheet metal modifications are made. A Sprite or Midget is limited to the 5” long manifold and a 2 ½” deep K&N filter if you want to stay away from really major surgery. However, from looking at the graph it is not difficult to pick out which manifold would be the best from a performance perspective. The 7” long manifold will fit a Mini with a cold air box installed, and probably a Morris Minor without too much trouble, other installations may have to be a compromise. Apart from the overall power increase through the usable power range one very obvious advantage is that it smoothes out the dip that always occurs on A-Series engines around 6250 RPM. Interestingly, if long ram pipes are fitted in place of the 16mm “shorties” the dip reappears in the power curve. In the past we have offered these manifolds chrome plated to reflect the heat from the exhaust, this is no longer an option, but we can ceramic coat them which of course does the same thing.
