i decided not go with the 350. my next big question is will a 305 exhaust manifolds bolt to my existing exhaust system from my old 4.3? i found a 305 out of a low mile truck my same year ('88) and i think im going to go with that.

anyone know?

Im guessing no, the exit points should be different but if its a good motor that is an easy fix any exhaust shop can do for you. See if you can get the y pipe with the enging and maybe you can make that work. Good luck.
