Edelbrock RPM Air-Gap Intake Manifold with Endurashine Finish for Mustangs with 351W Engines.Designed for street and high performance 351W Ford V8s, the RPM Air-Gap incorporates the same race-winning design that's been used on Edelbrock's Victor Series competition intakes for years. The air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. A larger cross sectional area and a taller carb flange than EDL7181 offer compatibility with large displacement, stroker 351W based engines.
Air-Gap manifolds are ideal for street performance from idle-to-5500 rpm.
Features Edelbrock's Endurashine finish. Made in the USA. Includes nitrous bosses. No provision for exhaust heated chokes and no exhaust crossover.
*Aftermarket 4-bbl carbs are not compatible with Ford Auto Overdrive Transmission (AOD) unless used with bracket SRK4000.

Cary: Fantastic. Thank you, Bill. Appreciate it. We've got a wide assortment of intake manifolds that are all made here in the States. We've got our multiple different series. We have a Performer series, an RPM series, a Victor series. We have you covered from mild to wild. If you're doing just a restoration project, you're looking for an aluminum intake versus that old heavy cast-iron one, you want to pull that two-barrel off, our Performer series is really going to fix you up and do what you need to do. That's got an RPM range from 1500 to about 5500 RPM. When you get into their Performer RPM series, that goes from 1500 to 6500. Really, it's just a little taller as far as the intake deck height itself.
When it gets to the higher end side of things, we have our Air-Gap here, and basically what the Air-Gap is, as you can see, it actually just allows air to go underneath the runners. It keeps the oil that's on the bottom of the intake from splashing up and putting heat on those runners. Gives you a cooler denser charge. Allows you to have a lot more horsepower when you're running down the road.
Bill: You mentioned the operating RPM for both the Air-Gap and the Performers, around 6500 RPM?
Cary: That's correct.
Bill:What if you get somebody who wants to spin a little higher than that. What else do you have?
Cary: We actually have the Victor series. We don't have it here today to show, but the Victor series is a single plane manifold with a little higher carburetor deck and allows you to spin it up to about 8500, or if you want to port that thing out, I've seen it go as high as 10,000 RPM.
Bill: Are all your different manifolds available in multiple finishes?
Cary:Yes, all the manifolds are available in multiple finishes. The satin finish is the primary finish. We have it available in a Durashine. We also have a black version. The coating that's on here is like a powder coating. It's a dipping process with multiple layers to it, with a clear coat on top of it to allow it to actually stay shiny just like this.
Bill: The black, is that a painted finish? Is it a powder-coated finish?
Cary: That is a powder-coated finish as well.Bill: Is it high gloss or is it a flat finish?
Cary: It's a flat finish. It's a flat finish; it's not a high gloss.
Bill: With the manifolds here, we know Edelbrock makes an excellent carburetor as well. It looks like you have everything else to install it.
Cary: Absolutely. Thank you, Bill. We actually have a lot of the other accessory items that you'll need to do the job right. What it takes to do the job right is really what we focus on at Edelbrock. We've got intake gaskets. We've got intake bolts. Because each of our intakes could be different depending on application, you may need a different length bolt. Plus, it's just a much more stylish accent to the intake install. A lot of items that get forgotten about when they do a carburetor in intake swap, is actually the carb studs, and that's one of the things that you offer here, as well, at CJ Pony Parts; to go along with that, any of the accessory items for the carburetor, breathers, air cleaners, as well. There's just a lot of different parts that we have. Anything to do the job right is what we're really focusing on to do.
Bill: Great. Thank you.
