Been too long.. got a huge update. Pontiac Larry put my 455 in his 63 Catalina for testing and two outings it went 7.87-7.86-.786 85.,xx mph. Last weekend went 7.79 then 7.76 85.09 on not so sticky track. That’s at 3800 lbs. race weight. Hopefully the Ventura is lighter. Outta be swapped in by Xmas time allowing! Combo is mild .40 over 455, erson tq50 228/235/110. Stock 72 intake , 9.1-1 CR pump gas, 10 inch tci and 3.64 gear I believe. Not too shabby!

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.
