Hey, it's a 2 way street. If hes got the motor, and the skills...
A close friend had a 55 Chevy running a 440/727/Dana in it. Got tossed out of 2 Super Chevy shows with it, and had to replace the mopar driveline with a 283/T350/(get this) 8 3/4 to sell it. Same guy has put 350s in Mazda trucks, V8s in all kinds of stuff..kind of an "anything goes" guy. I wouldnt want to hobble a car like that, but its free country.
