    Edelbrock 75511 Details


    The Edelbrock Performer RPM Air-Gap Oldsmobile 455 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. This 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 350-60519 for optimal performance. Not compatible with EGR or spread-bore carburetors.

    The First Dual-Plane Manifold with the Powerful Air-Gap Design

    Edelbrock has brought race-inspired technology to the street, again! The RPM Air-Gap is a dual-plane intake manifold with a dropped plenum divider that separates the intake runners from hot engine oil in the lifter valley. This provides a cooler, denser air/fuel charge for more power.

  • Maximum Power/RPM Range: 1500-6500
  • All Air-Gap manifolds are for non-EGR applications
  • Accepts most accessory brackets, including air conditioning, alternator, and coil mount
  • Most Air-Gap manifolds include rear water coolant outlets and dual distributor clamp locations (all include nitrous bosses)
  • EnduraShineâ„¢ option: Edelbrock's 3-step finishing process offers the brilliance of chrome without its cost or maintenance
