If you're working on a small-block 302 CID Ford V8 or a 331-347 stroker application, the Edelbrock Part #7521 RPM Air-Gap intake manifold is just what you need. This manifold brings the same winning technology found in our Victor Series competition intakes right to your garage.
Whether you're a hot rodder, a street machine enthusiast, or a bracket racer, this manifold is tailored for you. It's designed to deliver top-notch performance in the 1,500-6,500 RPM range, giving you that thrilling horsepower feel under the hood.
The unique Air-Gap design features an open air space beneath the plenum, which keeps the runners separated from the heat of the engine. This means you get a cooler, denser charge that translates into more power!
The 7521 RPM Air-Gap boasts larger runners—7% bigger at the plenum entries—compared to the standard 7121 Performer RPM design. This is especially beneficial for those larger CID stroker engines.
You'll find nitrous bosses included, but keep in mind that there are no provisions for exhaust heated chokes or exhaust crossover. If you're using Edelbrock carbs with Ford automatic overdrive transmissions (AOD), they work seamlessly when paired with the Lokar bracket SRK-4000. For more details, check out www.lokar.com.
The Edelbrock Part #7521 RPM Air-Gap intake manifold is an excellent choice for anyone looking to boost their small-block 302/331/347 Ford V8's performance. Get ready to hit the road with confidence!
