Genuine COMP CAM 12-600-4 Thumpr 227/241 Camshaft & Enginetech

Genuine COMP CAM 12-600-4 Thumpr 227/241 Camshaft & Enginetech High-Performance Lifters | LIFT: .479/.465" | Kit FITS Chevrolet SBC 283 327 350 400 5.7 5.7L
- The Legendary "Thumpr" Sound (107 LSA): The defining feature of this cam is the ultra-tight 107-degree Lobe Separation Angle. Why Buy It: This specific geometry creates early intake valve opening and long exhaust overlap, generating that highly desirable, rough, choppy, race-car idle that sounds far more aggressive than the cam actually drives.
- THIS LISTING WILL INCLUDE:
- 1)AUTHENTIC COMP CAM 12-600-4 THUMPR 227/241 HYDRAULIC CAMSHAFT - Hydraulic Flat Cam for Chevrolet Small Block 262-400. High performance street, stock converter ok, best with 2000+ converter and gears. Choppy/thumping idle.
- 16) ENGINETECH HIGH-PERFORMANCE HYDRAULIC LIFTERS
- Optimized Street Performance Specs: With a Duration @ .050 of 227 Int / 241 Exh, this cam places the power right where you play—between 2,000 and 5,800 RPM. Why Buy It: It gives you a massive boost in mid-range horsepower and torque, making it perfect for street rods and muscle cars that need to back up their bark with bite.
- High-Velocity Lift Profile (.479”/.465”): The lift is calculated at .479” Intake and .465” Exhaust. Why Buy It: This profile maximizes cylinder filling on stock or modified cylinder heads without being so aggressive that it destroys your valvetrain longevity, striking the perfect balance between power and reliability.
- Engineered by Competition Cams for SBC: Designed for 1955-1998 Small Block Chevys (262-400ci) using flat tappet lifters. Why Buy It: It allows you to achieve the sound of a high-compression drag car on a standard street engine. Tech Tip: For the best experience, we recommend pairing this with a 2000+ stall converter and headers to amplify that signature sound.
