I have never liked seeing a chevy motor in a ford. The most common engine swap is a 350 chev in any thing. I have a 71 chevy truck and I wanted to put a new motor in it. The sb 400 runs good but just has no flash. I thought of a North star. out of a cadi, but everone told me they're junk and have a weird water pump set up, to many problems. Talking to a mustang buddy of mine, he said what about a 4.6 out of a Mark 8, all alu block, double over head cams. 4 valve heads, a cobra motor. and you can get them cheep. It took me a day to find a complete car, running for $500. and a found a t45 5 speed for $400. So I'm all set up to install a FORD in a chevy Has this ever been done before?
