Description:
Edelbrock's RPM Air-Gap intake manifold (part #7521) is designed for small-block 302 Ford V8 and 331-347 stroker applications, with an optimized power band of 1,500-6,500 RPM. The Air-Gap design uses an open air space under the plenum to separate runners from engine heat, delivering a cooler, denser charge. Runners are 7% larger at the plenum entries than the standard Performer RPM 7121, making this a better fit for larger stroker builds. Nitrous bosses are included, but there is no exhaust crossover or provision for exhaust-heated chokes.

Q: What is an intake manifold? Why buy an intake manifold?
A: Air is routed through the air filter, through the throttle body or carburetor, and into the intake manifold. Once the air is inside the intake manifold it's distributed to each of the cylinders in equal parts. In order to increase the capacity of the intake manifold so that it carries more air into the motor for combustion, many people buy performance intake manifolds that incorporate a larger chamber where the air collects into the manifold. More air equals more power. So if you want more horsepower, an intake manifold is a great way to go about getting it.
Q: How do you install an intake manifold?
A: It depends on whether your car is carbureted or fuel injected, but either way, the good news is that it's located on the top end of the engine and therefore is easily accessible and won't require you to mess with any internals to change it out.
