I have a '84 Firebird with a 5-Speed and a 2.8 v6. Would a 305 or 350 bolt up to the trans? How much trouble would it be to switch?

Welcome to the boards.

Go here https://www.thirdgen.org/techbb2/sho...threadid=82546 to see what you're up against. Possible, but difficult & expensive.

you can get a v8 bellhousing and modify the clutch disk to mate it to the v6's 5-speed. Some guy did it. I forget his name.
