Level 3 camshafts are designed for moderately modified engines.

If you are uncertain as to which cam profile best suits your needs, please contact our technical support staff at 61. These camshafts works well with four-speed manual transmission.

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. Increased compression (9.5:1) is recommended for maximum output. 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. These camshafts provide excellent low end and mid-range power for spirited street, off road driving or mild marine applications. Works well with stock or near-stock engines and drive trains in a lightly modified street engine. Level 2 profiles are for individuals that require more power and an extended rpm range. 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. Stock or small cfm carburetor, small diameter tube headers and dual exhaust are recommended for maximum benefit. High vacuum, smooth idle and maximum efficiency are characteristics of these cams. 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.
