Here's the deal: I found a 425 cadillac motor from a late 70's cad for 175 bucks, and I was wondering if anyone knew anything about them (good deal for the cash, hp/torque, if they're worth it,etc). I already have a 472 (that I know are good motors)from a 1968 cad that needs a crank. Here's the question: Is it a good deal? If I got it, would it be better to leave it alone or does anyone know if the crank would fit in my 472? Cause if I could put those small combustion 425 heads on my 472, that would really make a good motor, or so I would assume. Can anyone help me out?
