1988 Caprice Classic Wagon

Engine change?? Is it possible to put a 350 engine in place of
the current 307 ? Without major issues. Any info would be
really appreciated. Thanks

It should fit in just fine, the block are the same size. Just be sure that you hook everything up as it was if you were putting in the original engine (Wiring, vaccume hoses).

I'd say to replace the radiator with one capable of cooling the 350 too.
