I have one in the 400 that just came out of the GTO. Engine is a YS 70 400 with 13 heads. Not a bad cam. Runs on 91 up here @6000'. Good power from 2000-4700 rpm. This is with a 4 speed and 3.55 gears. Also got 16MPG on a 500 mile trip running 65-70.

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.
