I bought a 3 core radiator for a 1976 dodge 1 ton with a 440 engine. With slight griding to the support brackets on the rad, it slipped into my 1971 demon with a 440 six pack. Used the water pump housing from 440 source with the inlet on the passenger side and hoses from the local parts store. Looks as if it was a factory install. Works great too as the fan assembly was taken from a 3/4 ton 318 pickup truck. Hope this helps
