1987 442 engine swap


Asked by Jul 18, 2016 at 09:36 PM about the 1987 Oldsmobile 442

Question type: Car Customization

I am looking to swap out my Olds 307 for
either an Olds 350 or an Olds 403. Is this
possible? Is one easier to swap out than
another? Any modifications needed?

1 Answer


All Olds small blocks are interchangeable so the Olds 350 will bolt right into place. My '72 Cutlass had an Olds 350, I now have a Chevy 350 and it wasn't that difficult either.
