Katech Gen V LT 427 Torquer Camshaft

Katech Gen V LT 427 Torquer Camshaft

Performance Camshaft Engineering for Naturally Aspirated Gen V LT Builds, Including 427ci Engine Combinations.

The Katech Gen V LT 427 Torquer Camshaft is designed for high-performance naturally aspirated Gen V LT engine combinations, including 427ci builds. Its profile features 235°/251° duration at .050", .657"/.660" valve lift with a 1.80:1 rocker ratio, a 113° lobe separation angle, and +4° camshaft advance.

This hydraulic roller camshaft features an 11% fuel pump lobe with 6.5mm fuel lobe lift. Supporting valvetrain components, fuel system configuration, and ECU calibration should be matched to the completed engine combination.

Katech's camshaft development draws on decades of racing engine experience and Optron Spin Cell valve motion analysis. Final power, idle quality, driveability, and operating range depend on engine displacement, compression ratio, cylinder heads, supporting components, and calibration.
