Just wondering....

Chris,you bring up a very good point.
I have not done enough dyno testing to know for sure but I can tell you about a customer of mine who has a very similar combo.
He has a set of 357 fully CNC'd AFR heads.
We tried his 357 cc heads first and our tq/hp where very poor below 3,500 rpm's.
I had set of 305 cc heads and the hp/tq picked up down below.
I guess we can lok at cam specs. ,boost levels,etc.
You can "overhead" a blown aplication also but it is much more difficult.
In the 454 listed above I am not sure what 10% under means as far as PSI.
I will try and see if I can find some of the dyno results.
