Edebrock RPM Air-Gap Oldsmoblie 455 Intake Manifold

The Edelbrock Performer RPM Air-Gap Oldsmobile 455 #7551 intake manifold is intended for aggressive street/ strip big-block Olds applications. Designed to optimize horsepower production from 1500 to 6500 rpm, this manifold will perform best with engines that have an aggressive camshaft profile that will take advantage of the increased flow this manifold can provide. The Edelbrock Performer RPM Air-Gap Oldsmobile 455 #7551 intake manifold features our popular Air-Gap design that separates the runners from the hot engine oil, resulting in a cooler, denser air charge for more power. This manifold is compatible with stock heads, but has been designed to work with our RPM cylinder heads #60519 for optimal performance. Not compatible with EGR or spread-bore carburetors. The Edelbrock Performer RPM Air-Gap Oldsmobile 455 #7551 also features a natural aluminum finish for a classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.
