I have run offy aluminum spacers (1/2") on top of
the cast iron 66 intake to adapt Holleys. Most
feel that a "riser" will even out the flow after
the throttle blade and will keep the fuel-air
mixture from hitting the floor at high velocities
but historically Pontiac tri-power intakes do not suffer from that problem as they were well designed by the factory for their carbs.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
