You are already borderline too-small with the 4.3. I would go the other way and put a 5.7 in it.

Anything else but a 4.3 also means re-gearing the outdrive.

I also have a 2355 but we have a 5.7L V-8 with "VORTEC heads" ( '98 & newer engines). Imo, you should be looking bigger not smaller. You've got to have the horses to get up on plane.
