I would like to return it to a pontiac engine and am interested in maybe a 350 HO, so I wouldn't have to change out the transmission.
Unless I am severly mistaken (happens more and more these days) the TH350 trans sitting behind the Chevy block will not mount to the Pontiac block without and adapter plate.
Yea, 350 tranny, might not fit behind a pontiac block, but a bigger TH400 would and you can normally find those that arent too pricy that will fit behind a 400! Hope you can find something that isnt too pricy and restore that machine to pontiac! Granted, it cost a little more to a lot more for a Pontiac engine, depending on what you are trying to do with the engine.
