windsor head porting
I am going to consider just the factory ford heads; I think that they are all about the same port sizes, I know the GT40s have larger ports, I hear of people using 351 heads all the time.
If I were to port my 1968 4v heads out to the maximum, and the 351 heads to the max , and the E7s adn gt40s all to the max, would would they all have the same sized ports?
How many ccs do I need to get a 302 up to 450 hp at 6000 rpm?
