Edelbrock Air Gap RPM

Thinking of trying out that air gap manifold on my 454. Running the Performer 2.0 now. It's ok but not thrilled with running my equal bore holley on a spread bore base. As well as hoping the air gap will allow my carb to run a bit cooler. Had some issues with fuel percolating due to hot fuel bowls. A 1/2 inch spacer seemed to help, but if the air-gap makes a difference, I can turf the spacer. What do ya guys think? Any opinions on the air-gap manifold?

I had air cleaner clearance issues as I have an SS hood. There is a drop base that will help. I plan to go with a cowl hood some time. Great manifold for my 383 though

You'll need a phenolic spacer no matter which one you run. Don't use a heat conducting spacer (aluminum).

The air gap is just a performer rpm with a space to collect dirt IMHO.

They both make the same power.

Re: Edelbrock Air Gap RPM

I have the performer RPM on my big block & love it. Barely fits under my SS hood. Did not like it so much when i was running Edelbrock carb. Fuel was boiling in bowl. Things are much better with the Holley.

Go big, or stay Home!
