it has been mentioned on other Mustang chat boards, you have to be careful with AFR and their flow numbers. If you have a question ask them directly, sometimes what AFR does is run a flow test with a 4.125 bore on their flow bench, which will jack up the flow numbers by a huge margin.
If you are not going to spin this engine into galaxy, I will narrow it down the intake selection to AirGap RPM, and the Performer RPM, but if you think you will spin it higher than that, then I say again AirGap and Victor Jr.
Confusing yet??????
