Performance Description
Delivers impressive midrange and top end power. Healthy sound. Economical price.
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.
