Will A 76 Buick 350 replace a Chevy 350?

No, overall size...Buick, Pontiac and Oldsmobile small blocks are primarily big blocks if you look at their actual dimensions. That was reason in 78 when all the GN cars shrunk in size that Pontiac, Olds and Buick had no real V8 so GM used chevy 305 and 350's. Got them into a lot of hot water.

not to mention, he's got the wrong bellhousing on his transmission.

you've got a 5 bolt bellhousing and buick uses the 6 bolt BOP (buick, olds, pontiac) housing.
