Aside from the obvious need to Relocate/ fabricate motor mounts, what else needs to be done to install a 250 in a 1950 3/4 ton truck? I plan to update running gear all the way though new trans, drive shaft, and rear end. Someone once told me that I would need to move the radiator forward for the engine to fit. Is that true? If so how difficult is that? I don't want to use an electric fan. Or is the 250 a poor choice in general for some reason?
