When switching from a buick 231 to a Chevy 305 you need to switch the frame side mount pedestals as well, best bets would be out of a grand prix or monte Carlo that came with a Chevy 305, or, if your in Canada only a cutlass with Chevy 305.Need to find correct motor brackets to fit clam shell frame moints. I bought aftermarket but are to narrow to fit the clam shell
