I am mocking up a 292 motor for my 52 g m c half ton to fit on a 1950 Chevy Chassis. The truck was in pieces when I bought it. It looks like the radiator support bolts to the crossmember that is under the front of the engine, which means the engine needs to come up about an 1 1/2 inches to clear the support. I have the rear Trans mount bolted, the bell housing is clearing the center crossmember. I have read a bunch of threads on this, but I'm still freaking out.
