I don’t think people realize what chris and I have done with a D port with no offset nothing or shaft rockers! This engine was down probably 15 hp up top because of the 421 merge collectors besides and this was all done on 91! Here’s a pic to show u what is different from 2018 without the head and intake work.

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.
