When swapping from a TH400 you only need to swap the yoke and move the crossmember back a bit. I have them off and on in my 70 GTO, the 455 kills them off pretty easily in stock form. Havent gotten one built yet, and mine always seem to have issues when I build them. So I keep a spare 400 handy..

love that OD tho, 1800 rpm @ 80 mph!!

About Us

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.
