Should work just fine. The bell housings are identical between 6 and 8 cylinder chevy engines. You will have to change out the u- joints and such, cause ones a GM-1000 and the other a GM-2000? Half and three quater ton trucks have different style u- joints and such. Your tranny is either a Saginaw or a Muncie.
