I have a 67 barracuda that was originally a slant 6 car. I used Schumacher mounts and C body HP manifold for the drivers side. I was really worried it would be a real pain in the butt. Boy was I wrong. Everything has been very nice. Got the exhaust put on yesterday and its great with plenty of room. So guys doing a A body with 383 and want HP Manifolds Use C-Body for the drivers side.
