Small Block Chevy Vortec Performer RPM
Performer RPM's are dual-plane, low-rise intakes with 180° firing order to
produce incredible top-end horsepower while retaining good throttle response.
Their larger plenums and runners match the free-flowing exhaust, high-lift cams
and other modifications of a high output engine. They are intended for
high-performance or competition engines that run up to 6500 rpm.
