TECHNICAL INFORMATION

& HISTORY-

Years cid Bore Stroke Main C/Rod

1955 was the first year of the OHV V8 Pontiac engine. 1981 was the last

year Pontiac built a V8, total built 14,624,886. After that, generic G.M.

engines were used. In 1961 Pontiac started reducing the thickness of the

cylinder block to reduce weight. From 1955-59 the engine cooling system

was of the “reverse flow” variety. This meant water was circulated through

the heads first, & then the block. 1955-63 engines used a cast iron timing

cover & a 4 bolt water pump. 1955-60 engines use the same crankshaft

flange & bell housing bolt pattern. A modern transmission requires an

adaptor. 1955-58 oil pumps are special, 1959-79 are all the same.

The deck height is the same on all Pontiac cylinder blocks- 10.24”. Conrod

centre to centre also stayed the same at 6.625”. All Pontiac engines listed

on the left use 1/2” size head bolts, although they are not all the same

length. These bolts screw into blind bosses in the outer walls of the block,

they do not enter the water jacket like a Chevrolet V8. This design elimi-

nated water leaks & block distortion. Some early engines had a forged

crankshaft as standard [55-62] and fully floating gudgeon pins [55-57]. In

1959 cylinder blocks used side mounts for the first time. A block mounted

starter did not appear until late in 1963. In 1964 oiling to the rocker studs

through the cylinder head was eliminated in favour of hollow pushrods,

the snout of the crankshaft was made slightly longer & the flywheel mount-

ing hub was enlarged. In 1965 the inlet manifold bolt holes were relocated

in the cyl heads & the Turbo 400 was introduced. In 1967 the bores were

increased to 4.12” and the 400 was born. Larger valve heads were also

used [2.11 & 1.77]. Also in this year 3 frost/core plugs per side were

introduced. 1968 saw the introduction of the high performance Ram-Air-

II with round exhaust ports. The 6.75” damper became std on all V8’s.

The Ram Air-IV came out in 1969 with many performance parts on the

engine. In 1970 the 455 was introduced by stroking the 428. By this time

the engine had 5 engine mount holes per side. From 1971 on, low lead

fuel was used & the compression ratio was dropped into the 8’s, a Unitized

electronic distributor was also used on some models later in the year. The

points & Unitized distribs were phased out in 1974, replaced with the

common HEI type. During the mid ‘75 production year blocks were rede-

signed with lighter main saddles & thinner cylinder walls. From mid 76,

some engines had only a “hub” and no harmonic balancer.

BY13105 Ultra Serpentine conversion- pwr stg version .. £939.85Use Chevy power stg pump BYP304 [keyed version]

This March kit enables you to convert your

Pontiac to a Serpentine style belt system. The

pulleys & brackets are all made from Billet

aluminium in the USA, not China. If you have

air-conditioning, a different kit will be required.

This kit will not fit Chevrolet or Oldsmobile

powered Pontiacs. Your engine must have a 1968

or later 4 bolt balancer, without a “V” groove

built into the outer edge & a 1969 or newer 11

bolt 4.5” water pump. The pulleys are clear

powder coated for protection. The alternator &

water pump pulleys both have nose covers, for

that sleeker look. Other kits are available both

from March & Billet Specialties, but they may

be more expensive. Using a smaller diameter

crankshaft pulley will save horsepower, but the

water pump & alternator will turn slower- not

good if you spend a lot of time in traffic!

higher end gap. Please read the instructions. Severe damage will take place otherwise. Slightly less igntion timing can be used with these pistons. To obtain the

compression ratios listed below, use a .010” deck height for piston, & a .039” thickness gasket. 389,428 & other pistons available to order.

The Company “United Engine & Machine” in Nevada, make Silvolite std cast pistons, “Keith Black” Hypereutectic performance pistons, & now “ICON” forged

pistons. They have a long history of manufacturing & this new forged line of pistons incorporates all the latest technology. Ideal for street or race. These pistons use

wider clearances & therefore could make more noise when cold. Made from 2618 material, with fully machined crown & cutaways. Advanced accumulator & mini

groove technology. Diamond finished skirts, drilled oil returns, drilled or broached pin holes, spiral lock “circlips”. The compression ratios listed below, use a .010”

deck height for the piston, & a .039” thickness gasket. Pistons for other models available to order.

These pistons are forged. [Key: F/T - Flat Top: P/U - Pop Up or Raised: D/C - D-Cup: S/D - Step Dish:

EDELBROCK Performer RPM flat tappet Cam & Lifter Kits

Designed for street high-performance applications, Performer RPM cams provide power from 1500rpm to 6500rpm with the right cylinder heads. These hydraulic

lifter cams are dyno matched to Performer RPM manifolds for high-rpm horsepower while still maintaining acceptable low end torque. With 10-12 inches of manifold

vacuum at idle, Performer RPM cams have more lift & duration than most street cams. Adjustable valve train will be required to enable the preload on the hydraulic

lifters to be set. Vale springs will need to be replaced, & the manufacturers fitted lengths strictly adhered to. Do not use the std timing chain set.

NOTES: Always buy the correct valve springs for your camshaft. This can avoid mechanical failures later on. Do not use a standard timing set with your

performance camshaft, as they may have “retard” built in to them. Do not use performance camshafts with non-adjustable rockers. Fuel injected OEM

engines, generally use a special camshaft. Because many modern oils do not have the “ZDP” package of additives required for a flat tappet cam, you need to

mix a container of BY159 with your oil each time it is changed. Valvoline Racing oil has the “ZDP” package already in it.

heads in two combustion chamber sizes, 72cc & 87cc. Complete heads include- guide plates,

7/16” rocker studs, bronze valve guides, stainless valves, etc . The heat crossover is machined.

350 engines may require notching of the block for valve clearance. Head bolts BY8561 will

be required, as three of the head bolt bosses are raised higher than the std head.

Technical information: There are many variables involved when selecting p/rods for a performance

engine. Block height, cylinder head “thickness”, type of camshaft, rocker type used, lifter or

tappet plunger depth, etc. If you are unsure about the selection criteria, ask for a copy of page 293

from the Comp-Cams catalogue, when you order your valve train parts. Always check that a

clearance exists between your pushrods and the tunnels in the cylinder heads. Sometimes clearancing

is necessary. If you need an adjustable push-rod length checker, to help work out your push-rod

length, see the tools section in the Real Steel catalogue or on the website [accessories, page 12].

VALVE GUIDE REPAIR

Valve guides are cast into most Pontiac cylinder heads. They

can be reclaimed by using “steel backed liners”. This job is

listed on the engineering page. In the event of a damaged

guide, the below item can be used. [semi-finished]

high spring pressures are common. The lash cap helps prevent

damage to the valve tip.

STANDARD VALVE STEM SEALS

If oil can get down the valve guides into the cylinder, this will lower the octane rating of the fuel andyour engine could pink or detonate. Umbrella seals are normally used where the spring is a single typeand there is enough room inside the spring for the seal. This type of seal moves up and down with thevalve - shedding the oil. The Teflon & Viton seals, generally require the O.D. of the valve guide bossto be machined. They fit tightly onto the guide boss, & do not move. Teflon is good to 450f & Vitonto 500f. For tools to machine the top of the guide see the accessories section page 12.

These rockers are made from 8620 chromemoly steel in the

USA. The reciprocating weight of this rocker can be lighter

than bulky aluminium rockers. The design makes this rocker

very stiff with an accurate ratio, ensuring you get the full lift

at the valve. Roller tip reduces friction and wear. A power

increase will be obtained over std rockers. Do not exceed an

open pressure of 350 lbs.
