I'm swapping an lg4 (305 carbed) Into an 89 firebird and have the chance to get a 350 longblock from a 91 chevy van for cheap. Will my 305 intake manifold and everything else bolt right up to the 350? Also mines a 5 speed- will I need a diff flywheel or anything since the 91 350 is a 1 piece rms?

everything will bolt on fine. they are the same block dimensions externally. . your 89 should be a one piece rear seal as well. my 86 was.
