I am using a holley 750 double pumper on top of this edelbrock rpm airgap and leaves no room for even the thinnist air cleaner element can anybody give me a suggestion i really don,t want to cut the hood under the fake hood scoop.

Sorry you have this problem. I'm trying to stuff a 351W into a '66 Coupe, so I've the same sorts of issues.

The RPM Air Gap intake is inches (at least one, but less than two) higher than Performer/Performer RPM intakes. That may be your best alternative - try another intake.

Yeap, the best thing you can do is to try another intake.
I was thinking in put an air gap 351W in my 73 sportsroof with ram air hood but I'm afraid of the clearance. Your rpm air gap is a....?

No I don't think he is. He just built a stroker 351(418 ci now) and put it in his car this past weekend. Final numbers 563 ftlbs torque @ 3600 rpm and 499 hp @ 5900 rpm. I suggested a cowl induction hood but he wants to keep the Mach look. Any ideas if a shaker would work with his set up?

On my 460 swap, I had a clearance problem. I am running a Deamon 750 Double pumper. I took an aftermarket 289 HI-PO
air cleaner (2"tall) and cut the center out of the base. Then I got a cheap 8" Mr. Gasket air cleaner from Advance Auto Parts ($8.00) Cut the bottom off it. Then, siliconed the two base pieces together. This gave me a drop base 2"X14" air cleaner. It looks good on the car, can't tell it was reworked, and the 460 still breathes good with it....And the stock hood closes with about 1" clearance.....

Are you really sure you want to run the Air Gap anyway? it is rated 2500 - 6500 RPM. You will not have much at the low end at all. How about the Performer RPM? 1500 - 6500 RPM and suggested carb is a 750 CFM. This should only be about 0.9" taller over stock in the back and 0.55" over stock in the front.
