Re: Another Ford in GT/AA
 

For a cylinder head that has the volume of a Cleveland, with a large valve size, and 11.0 to one compression, 324HP makes it a pretty favorable combo. I dont know many heads that will flow what a Cleveland head will. They are about the best out there.

I wish I had a set of those good CC Cleveland heads and intake for my old ride.

Re: Another Ford in GT/AA
 

Actually the Cleveland heads are not that big, a lot of cc but they are only 2.80 Inches of cross sectional are at the short turn.

2.8??? That is good for about 470 inches to 6500 RPM with zero limitations on HP. Gesso Pete, we are more like 2.2 with a 14 degree valve angle and a hundred more cubic inches to do the same thing. Want to know the equation for CSA required to prevent limiting HP?

CSA required* = bore * bore * stroke * RPM/0.00353*(614fps)

*minimum cross sectional area throughout the length of the intake port. For those too lazy to do the math, there are calculators where you can just plug in the numbers required. (If you want to calculate fps numbers that is fine, just remember that it is required that you double measured fps to obtain actual.)
