Jim, my combo in my sig, uses an 8" PTC converter. 33.5" tire with 4.30 gears. Dyno'd at 960 HP as well.
With the 1.80 PG, I went a best of 1.09 in 60'. Routinely 1.12s. Launched at 5900 RPM. Might need a better converter, but also some chassis work. Shocks, 4 link, tire pressure, wheelie bar height, etc.

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.
