Older 400 in 1972 A body
I picked up a nice 69 400 w/62 heads from good guy here on the boards. If I wanted to run the engine in my 72 lemans, can it be done? I believe the engine mounts are different. What would I need to do to make it happen? Thanks

OK, I'll start by saying Butler has adapter brackets.

It's a direct bolt in as long as the '72 LeMans came with a 350 Pontiac or 400 Pontiac.
Only time, you would have issues with the '69 & earlier block, is if the LeMans was an original 6 cyl car, or the '72 LeMans was factory optioned with a 455 D port or 455 HO engine.

It's 100% drop in as would be any 421, 428 or even any 455 since they where cast with all of the 5 needed bolt holes on each side of the block to go into the 70 and up F body cars.

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.
