Performance Description: These cams offer extended rmp range with emphasis on upper bottom and top end power.

Engine Application: Level 3 camshafts are designed for moderately modified engines. Intended for performance hot street/strip and performance marine applications.

Recommended Modifications: These higher lift and longer duration camshafts demand close attention to rear end gearing and tire diameter combinations. The secret here is to pick a ring and pinion gear set and tire diameter that keeps the engine in its optimum rpm power range. Automatic transmissions with an aftermarket high stall torque converter and manual transmissions. Headers, dual exhaust, larger than stack carburetor, performance manifold and increased compression (9.5:1 to 10.5:1) are required. Mild porting and larger valves will improve performance.

Product Characteristics: Moderate lope at idle. Extended rpm range with emphasis on upper bottom to top end power and a strong mid range.
