Summit Racing™ Pro SBC Big Nasty Stroker Edition Hydraulic Retro-Fit Roller Cams

Summit Racing™ Pro SBC Big Nasty Stroker Edition hydraulic retro-fit roller cams are American-made performance camshafts designed for older small block Chevys equipped with flat-tappet blocks. These kits update engines to the modern LS firing order (1-8-7-2-6-5-4-3) to improve harmonic stability and power. They offer high lift and aggressive, yet street-manageable, profiles, available in multiple stages.

Key features and technical details:

* Design: These are "retro-fit" cams with smaller base circles, designed to fit into early SBC blocks
* LS Firing Order: By using the 1-8-7-2-6-5-4-3 firing order, these cams enhance bearing life, reduce vibrations, and provide better power
* Performance range: The "Big Nasty" and related stages range from daily-driver friendly to aggressive "street/strip" cams
* Components: Kits typically include the cam and drop-in link-bar style hydraulic roller lifters
* Requirements: Requires a cam button, and a melonized or composite distributor gear
* Source: Precision-ground in the USA

Performance highlights:

* Power: Tests show these cams are capable of producing over 450 hp and 450 lbs.-ft. of torque, with some variants pushing over 500+ hp depending on engine build
* Engine type: Ideal for 383, 400, or larger SBC stroker engines
