You can pick up truck Hemi's pretty commonly now. The truck timing cover has the accessories mounted up high and is not as good looking as the car Hemi timing cover because of this. They are intechangable though it is actually the interference with the frame rails of the classic car that ususally dictates using the truck or spending big money on a custom acc drive system. If you get a car Hemi priced right, you can always just swap the timing cover.
