LS7 Track Attack Hydraulic Roller Camshaft

The Katech LS7 Track Attack camshaft is a maximum effort hydraulic roller camshaft engineered for all-out competition use while retaining street-driveability. Designed for LS7 or LS3 416 engines, this camshaft is Spintron validated to 8000 RPM and boasts a powerband focused on a strong mid-range and very strong top-end performance. Katech claims this camshaft will guarantee 600 RWHP when combined with their LS7 CNC Port, a free-flowing exhaust system, and an appropriate intake manifold. It has demonstrated significant power gains, including 616 RWHP on a customer vehicle, and with proper calibration, can exhibit surprisingly good street manners for its aggressive profile. With impressive performance figures, this camshaft is capable of achieving 145 MPH in the quarter-mile, with a 9-second potential. On 93 octane fuel, it can produce 700 HP and 590 lb-ft of torque with an MSD intake. When running E85 with a 13.5:1 compression ratio, power increases to 730 HP and 617 lb-ft of torque with an MSD intake, and further to 757 HP and 617 lb-ft of torque with a Comp LSXHR intake. Katech emphasizes the durability of their camshaft packages, leveraging over 45 years of racing industry experience and proprietary technologies like Optron spin cell analysis for valve motion. Their involvement with the C5-R race program ensures a focus on valvetrain design with no history of failures due to insufficient design. However, users must check piston-to-valve clearance, and forged pistons with larger valve reliefs are highly recommended for optimal compatibility and safety. Suggested valvetrain components include Katech Ti/Mo Valves, a Katech/PSI Valve Spring Kit with H13 Retainers, and Katech/Johnson 2116 Lifters.
