Pontiac Engineering "Good Ideas"

1) Air Gap manifold keeps the intake charge cool

2) Intake mainfold can be removed without having
to remove the distributor and "retime" the engine.

3) Valley pan gasket can be one piece vs 4 on
the Chevy.

4) Built in Oil Separator on valley pan vs a
separate pressed in part in the valley on the
Chevy.

5) Water pump design allows for superior cooling vs a Chevy using factory parts. A stock
cast impeller Pontiac pump has better flow than some "racing" pumps for Chevys.

6) Deep timing cover allows one piece cam excentric /fuel pump lever contact with the fuel pump
vs needing a fuel pump pushrod. Fuel Pump excentric
goes bad on a chevy (part of the cam) you replace the cam and the lifters. On a Pontiac the cam and
lifters do not need service and you change a cheap part.

7) Pontiac uses a Cam Thrust Plate to hold the cam in
the correct alignment under the timing cover. The Chevy needs a special "Cam Button" or reinforced
timing cover if you put in a high perf cam.

8) Pontiac timing cover has provisions to raise the
engine from the bottom (motor mount bolts removed) to
remove the pan on some engines. The Chevy has no cast
in provisions to support the engine.

9) A Pontiac Timing Cover (using a balancer spacer)
will allow a Motor Plate to easily be installed under
the timing cover and the plate will be mounted securely by 6 bolts. The Chevy block has a couple of
bosses on the front of the engine that allow engine
brackets to be installed but the design is not very
strong for high hp engines.

And the list goes on and on.
