I recently purchased my first Mustang for my 15 year Old son. I have a 1967 GTO that I have had since I was a teenager, so he has always wanted a American Muscle Car. Anyway, I am not much of a Ford man, at least with cars, never had anything but Ford trucks. Any way I just do not know a whole lot about the late 60s early 70s cars/motors. I purchased the car and it has headers and a high rise intake with a 4 barrel carb. the rear intake gasket had blown out so I got a new gasket set for a 4 barrel motor, then I realized something was up, I then did some research and found out that I have a 2V motor. My Question is.. Am I gaining much with the four barrel and high rise or should I put a 2 barrel back on it??? I noticed the huge difference in the head ports which makes me think I may be just dumping fuel into a hole with not enough air flow. Any hints or advice about anything to do with the car would be appreciated.
