These new intake manifolds are 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. R&D testing with a 355 cid Holden engine produced 405 flywheel horsepower and 427 ft-lbs. of torque with #7594 RPM intake and stock cast iron cylinder heads. Matching Performer RPM aluminium cylinder heads coming soon.

PLEASE NOTE: This manifold does not suit engines with roller cam and lifters!!!
