1972 cutlass supreme
I have a 72 cutlass but I am switching the 350 for a 403. Does anyone know if the 350 manifolds will work on the 403? If not, any advise on this swap? Chrisroberts376@yahoo.com

Welcome, Straight swap. The only difference that may delay you are on the exhaust manifolds where they exit. The flanges could be different where they bolt to the down pipes. Good luck with it.
