The Chevrolet SysteMAX camshaft was designed by Holley to maximize the density of the intake charge, provide a more combustible air/fuel mixture and deliver a higher constant port velocity. On the street this means more usable and efficient power throughout the RPM band.
Lifters
The lifters that come with the SysteMAX kit are flat tappet hydraulic.
Timing Chain & Gears
The double roller timing chain and gears provide for more precise timing and power.
Intake Manifold
The Holley SysteMAX dual plane aluminum intake manifold features large, smooth-flowing runners, a high-rise plenum and it makes power from off-idle to the 5500 RPM red line limit of the SysteMAX package. It's like the old LT-1 manifold only better. Has a square mounting flange and no EGR provision.
SysteMAX Recommendations
It's recommended that a 4-bolt main short block be used, although a good 2-bolt main short block can also be used. Minimum cylinder head valve size requirement is 1.94in intake diameter and 1.50in exhaust diameter. Compression requirement is 9.8:1. Holley testing was conducted with a 750 CFM vacuum secondary carburetor, P/N 0-3310. A good set of 1-5/8in tube headers used in conjunction with some high-flow/low back pressure mufflers won't hurt you either. If you're running an automatic transmission a 2,000-2,500 RPM stall converter will help lower drag strip times. New, top quality gaskets for your specific application are required separately and are not part of the package.
