New from Edelbrock – the RPM Air-Gap intake manifold for Holden 308-383ci engines with VN style cylinder heads. These manifolds are a dual-plane design and are tuned for excellent throttle response.

Official Release:

Edelbrock is excited to be shipping its new RPM Air-Gap intake manifold for Holden 308-383 c.i.d. engines with VN style cylinder heads.

This new Edelbrock RPM Air-Gap intake manifold is designed for street and high performance 308-383 c.i.d. Holden V8 engines that utilize the 1988-98 Holden VN cylinder heads. These RPM Air-Gap manifolds are a dual-plane design that are tuned for excellent throttle response from 1500 to 6500 rpm. They feature an open air space that separates the runners from the hot engine oil for a cooler, denser charge for more power. This intake manifold is available for carbureted applications (#7594) and also with injector bosses for EFI applications (#75945).

Testing with a 355 c.i.d. Holden engine produced 405 flywheel horsepower and 427 ft-lbs. of torque with our #7594 RPM intake and stock cast iron cylinder heads. This manifold has been designed to fit both stock 1988-1998 EFI style heads and the Edelbrock Holden VN Performer RPM cylinder heads.
