Usage Recommendations & Reviews
Performance: Reviewers on Summit Racing generally praise this cam for its strong mid-range torque and power delivery in properly equipped small-block Chevy engines. It is described as being very responsive and effective in a variety of street applications, including in heavy trucks.
Idle Quality: It is known for having a distinctive, aggressive “muscle car lope” at idle, which many users appreciate.
Required Components: To achieve optimal performance and drivability, sources like Winners Circle and Summit Racing highly recommend using a higher stall torque converter (2100-2600+ rpm), headers, appropriate gearing (at least 3:73), and a compression ratio of at least 9.0:1. Aftermarket valve springs are required; stock valve springs cannot be used.
Compatibility Note: It is not suitable for LT1/LT4 engines or some factory small blocks from after 1985 and is not compatible with computer-controlled systems.
