New to this site, I have a 51 Chevy 2 ton with a dump bed that my construction company uses as a trash truck. The 1953 235ci just is not cutting it at 8000 ft of elevation in the Colorado Mountains. I just picked up a 350 and The plan is to swap engines but leave the existing transmission. The clutch, tranny, e-brake and PTO all work fine and I don't want to mess with that end of It. I have been told by some friends that If I go with a pre 1964 bellhousing that it is a clean swap. Does anyone know if the trans can stay in the same position without modifying the firewall (does the distributor fit?), and I have been reading about moving the steering box slightly in lighter duty trucks, I assume it will be tighter on this truck. Has anybody out there done this swap? Chris
