Performance Description
Intended for the hot marine/strip application, these cams offer extended rpm range with emphasis on upper bottom to top end power with strong mid-range.
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.

Performance Description 2
Dual purpose hot street/strip camshaft. Delivers strong midrange and top end torque and horsepower.
Engine Application 2
Level 4 camshafts are designed for heavily modified engines. They have a definate lope at idle and are best suited for dual purpose hot street/drag strip, hot marine and oval track applications.
Recommended Modifications 2
Headers, dual exhaust, large cfm carburetor, performance ignition and increased compression of 10.25:1 and above is required. Cylinder head modifications would be beneficial. Use with automatic transmission with high stall torque converter or manual transmission. Close attention to proper ring and pinion gear set and tire diameter is imperative.
