Cleaning the shop area last night found a 9/16" UHMW spacer that I ran on the Gutsram intake. Due to height limits in a stock chassis/hoodline car I used a flat aluminum top for the AFB's. The spacer went between the intake and top for more plenum volume. With the spacer I picked up almost a tenth.
I have also found with both intakes a Shear Plate under the carbs is worth about a tenth,

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.
