Im using a carbed setup, its going in a '66 Mustang, and im also using the distributor for the '66 with the hardened gear, so im not worried about it working with any computer or anything. I just need to know that it will fit in (they are the same base circle), I wont smash a piston into a valve, and that the cranks are the same for both engines so that all I will need to do is change the firing order at the distributor cap.
Also, are the timing gear sprokets different?
