Want to put a pontiac 400 in a chevy set up

Hello ,
I have a 32 ford set up for a chevy motor but I would now like to put my fresh pontiac 400 tripwr set up in it . Is there a adapter motor mount that someone sells to do this or do I have to redo my frame mounts .

Thanks, Tony

do you already have the common 70s up clam shell style mounts? if so just get ones for pontiac etc engines. they are just a tiny hair different is all, than chevy ones.

Chassis mounts

Now I'm not quite sure how the mounts are setup on your chassis, but I do know that apart from being a little wider than your typical Chevy, the Pontiac block mounts are in a slightly different place. If your chassis mounts are short in length, you may not have a single problem at all, considering that late Pontiac mounts are nearly five inches from nut to bolt-hole. However, if the mounts are long, you might have interference on the front side. Do note however, that the poncho's mounts are further apart laterally than your typical SBC. Try stuffing a 462 stroker Pontiac in a 73 Camaro, it won't work unless you use the chassis mounts from a similar F-bird. (Which are nearly 2 inches shorter in height, for all of you keeping tabs on my knowledge of such things.) Take note on not only the distance between mounts, but also their length, and distance from the front of the block. It may, simply, drop right in depending on your style of chassis mounts,
