Edelbrock's Performer RPM Air-Gap intake manifolds incorporate race-winning technology that's been used on Victor series competition intakes for years. The open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. So, the air/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Performer Air-Gap manifolds, from idle-5,500 rpm up to 1,500-6,500 rpm.

Q:

Any fitment issues with a stock 351w? (1984) Stock heads ect. Will it be a problem if i want my idle lower than 1500? I see its listed as 1500 and above

Asked by JORDAN on July 20, 2018

A:

Thank you for your question. Edelbrock 7581 Performer RPM Air-Gap intake manifold will have no problem fitting your factory 351W heads. You will be able to set your idle speed below 1,500 rpm. The basic operating range you referenced gives you an idea of the power band where this manifold is most effective.

Beautiful Intake!!

EDL-7581
I just bought this #7581 intake for my 351w in my mustang. I have stock heads and installation couldn't have gone better. The intake comes with papers that show bolt patterns, torque setting, and all the thread sizes of everything on top of the intake, for plugs or whatever you use. Upgrading from a dual plane offenhauser intake, this is a noticeable difference in power and also added a really great sound to my exhaust. After putting this on, my mustang feels open, like it can breathe. This is my daily driver, and my really only going up to 4,000 rpm on the road, this just has power through the entire rpm range!! This is in my opinion the best looking intake. ...read more

Looks really good and performs even better. I used an Hei setup on this and had to shave just a bit off the intake and distributor to clear.

Looks great. Had to clearance a bit for an HEI distributor. Fit exactly as expected. Bolted up perfectly. Wish it had a milled center divider. Will have to run a carb spacer to get the same effect.
