Engine Application
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
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.
