Performance Level 3 - Ultra Beast - Upper mid-range to top end power. Emphasis on top end.
Level 3 camshafts are designed for moderately modified engines. Intended for performance hot street/strip and performance marine applications, these profiles have a moderate lope at idle and offer an extended rpm range with emphasis on upper bottom to top end power and a strong mid-range. These higher lift, 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. These profiles perform well with four-speed manual transmissions or automatic transmissions if a high stall torque converter is employed. Headers, dual exhaust, larger than stock carburetor, performance manifold and increased compression (9.5:1 to 10.5:1) are required. Mild porting and larger valves will improve performance.
