If you’re looking to give your Chevy V8 a little extra love, the Edelbrock part #7520 Air-Gap Dual-Quad-O intake manifold is just what you need. Designed specifically for street 396-502 c.i.d. engines with 1975 and earlier oval port heads, this manifold is all about enhancing your driving experience.
This intake stands 7/8" taller than the low-profile C-66-O dual-quad intake, which means you’ll notice some serious performance improvements in the 1500-6500 rpm range. Whether you're cruising down the highway or hitting the open road, this manifold is built to deliver.
One of the standout features of this manifold is the large runners that boast our unique Air-Gap design. By separating the runners from the hot engine valley, you get a cooler, denser charge that can make all the difference in your engine’s efficiency.
The Edelbrock RPM Air-Gap Dual Quad Manifold is an ideal match for Chevrolet 396-502 Big-Block V8 engines with large oval port heads. Get ready to feel the difference as you hit the gas!
