If it could/would work I would have been machining and selling right now.........but I don't think there's any way it can be done. I actually tried to install a JGC on my '69 Barracuda (318). The exhaust outlet actually hits against the starter before you can even get a bolt into the head. It doesn't just get close to the starter it runs directly into the top of the starter. I had a mini in my car at the time so I can say with confidence that it can't be made to work. Spend the better part of a day trying to get it to fit but there was no way. The passenger's side on the other had was "made" for the A bodies!!!!!
