8ba car and 8rt truck shared the same block and internals. The car had different water pumps than did the trucks. Trucks were wide belt and and the cars were narrow belts in addition to the way they mounted to the frame. The big trucks had a 1/2 bell housing to mate up to the 4 speed crash boxes. 8rt heads were lower compression than the cat 8ba heads. Later model EAB heads were the highest compression of the 3 but all will interchange. Photos. We like photos.
