Holley SB-Chevy 5.0L - 5.7L 1962-87
510-300-503-1
SysteMAX II SB-Chevy
SysteMAX Requirements:
Holley testing was conducted with a 750 CFM vacuum secondary carburetor, #510-0-3310. A good set of 1-5/8'' tube headers, used in conjunction with some high-flow/low-back-pressure mufflers is definitely recommended. If you're running a beefed-up TH-350 automatic transmission then a 3,000+ RPM stall converter will help lower drag strip times. If you're running a TH-700R4 automatic transmission, a 2,500+ RPM stall converter will perform best. For all-around great street/strip performance a rear axle ratio of around 3.55 should be used. A set of the Crane, (#270-11750-16), roller rocker arms is also recommended. New, top quality gaskets for your specific application are required separately and are not part of the package.
