PERFORMER RPM® POWER PACKAGES
Performer RPM Power Packages have a broad operating range for improved performance in street applications in the 1,500 to 6,500 rpm range. They use Performer RPM or RPM Air-Gap intake manifolds, Performer RPM cylinder heads and Rollin’ Thunder hydraulic roller camshafts. This combination delivers great throttle and improved low-end torque while maintaining great vacuum at idle. Performer RPM cylinder heads include top-quality valvetrain parts for maximum power and are available with spring packages for use with both hydraulic flat tappet and hydraulic roller applications. Because of the high rpm capabilities of these packages, a high-volume oil pump, adjustable rocker arms and High performance pistons with 9.5:1 compression are recommended.
