There is a guy who put a Hemi in a Pantera and more recently a Chevy, whichever the 600hp supercharged one is, in a Pantera.
In both cases the modification is so extreme, it's difficult to recognize the car as a Pantera.
In any case, using the Chevy is like putting tits on the middle linebacker of the NY Giants. Basically, something you can show off in the locker room and take lots of pictures with but as far as function goes, you may as well race a donkey?
