Crower 61391 Hydraulic Roller Camshaft

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. These camshafts provide excellent low end and mid-range power for spirited street and 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. Works well with four-speed manual transmission. Designed for lightly modified street engines.

Performance oriented street, use with turbo, supercharger and/or nitrous. Will work with stock springs and ECU.
