Performer RPM or Air Gap Intake?

[sawking]

I was looking for some input on these two Intakes. The motor has oval port 781's with the bigger valves. 9.5 compression with a xe268 cam. Around 450 hp. I was wondering if there is going to be much difference in these intakes. Max RPM will be around 5800. Thanks

if you block the ex cross over and ran a l88 valley pan on the performer RPM i think they would be close so if you have the room run the air gap if you do not run the RPM

Friend of mine is running the Air Gap intake on a 501" Ford and it works great. Like Pat said, if you've go the underhood room go for it!! If you don't have room go with a cowl induction scoop and make room for it.
