my motor is a short deck out of a 77 suburban with the eagle stroker crank(+.250), the +.25 eagle H beams, and JE 13:1 pistons with C&A ZGTF rings. Intake is a holley strip dominater single plane with a 850 cfm double pumper. As far as hood clearance it is a good thing there is already a hole in the middle of a trans am hood. the baseplate if the carb is just bout even with the bottom of the hood with a 1" spacer.

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.
