The 4 bolt Chevy trans pattern is pretty much standardized with a few exceptions., It is the bell housing to motor and starter mounting/flywheel size problems that most encounter. Not relevant in this case. The pattern fits Muncie, Saginaw, Stewart and others. This is just one example why Chevys are used so much in all forms of swaps. Everything fits everything, almost. Fords are not like that at all. You can find Chevy built motors in trucks, cars, boats, motorcycles, military vehicles and planes. (Pratt and Whitney radial engines for bombers and cargo. Every part built and assembled at Tonawanda. WWII.)
