Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhance throttle response and low end torque in vans, trucks, passenger cars and mild marine applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum efficiency are characteristics of these cams. Stock or small cfm carburetor, small diameter tube headers and dual exhaust are recommended for maximum benefit. Intended for stock or near-stock engines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic transmission with stock converter or four-speed manual transmission.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.

Level 2 profiles are for individuals that require more power and an extended rpm range. Works well with stock or near-stock engines and drive trains in a lightly modified street engine. These camshafts provide excellent low end and mid-range power for spirited street, off road driving and mild marine applications. Modifications that should accompany installation of these cams include small diameter tube headers, low restriction dual exhaust, aftermarket manifold, increased cfm carburetor and reworked or performance ignition. Increased compression (9.5:1) is recommended for maximum output. Aftermarket torque converter with slightly higher stall speed is recommended because stock factory converters do not allow the engine to provide adequate idle speed and off idle performance. These camshafts work well with four-speed manual transmission.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.

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.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.

Level 4 camshafts are designed for heavily modified engines. These camshaft have a definite lope at idle and are best suited for dual purpose hot street/drag strip, hot marine or oval track applications. These grinds exhibit strong mid-range to top end torque and horsepower. Headers, dual exhaust, large cfm carburetor, performance ignition and increased compression of 10.25:1 and above are required. Cylinder head modifications would be beneficial. Use with standard manual transmission or automatic with high stall torque converter. Again, close attention to proper ring and pinion and tire diameter selection is imperative.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.

Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines and chassis. Extensive cylinder head modification, bigger valves, lightweight valve train, titanium valves, maximum flow carburetion or fuel injection, racing gas, alky or nitro, magneto or electronic ignition, performance rod and crank assembly and increased engine clearances are required for maximum benefit.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 619-661-6477.
