I'm going to take it back again and take out the air filter. It there is a noticeable difference than I will make a new air inlet tube to the throttle body. In my opinion it should make at least 550hp I'm a hundred off somewhere and I think it is starving for air.
Don, I worked on his '63 1/2 fastback. His son and Ford are coming out with a new project in remembrance of his father.
