Designed to improve performance on the street or racetrack, the RPM Air-Gap 351 Cleveland intake manifold features an open space that separates the runners from the hot engine oil resulting in a cooler, denser charge. The Edelbrock Air-Gap design utilizes the same race-winning technology that's been used on Edelbrock's Victor Series competition intakes for many decades. The RPM Air-Gap manifold for 351 Cleveland engines is designed to complement Edelbrock's 351C Performer RPM cylinder heads 350-61609, 350-61629 and also works well with 4V and 2V cast iron Cleveland heads.Installation Notes:
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.
