Katech Gen V LT1/LT2 Torquer Camshaft

Katech Gen V LT1/LT2 Torquer Camshaft

Performance Camshaft Engineering for Gen V LT1 and LT2 Engine Builds.

The Katech Gen V LT1/LT2 Torquer Camshaft brings Katech's engine and valvetrain development experience to LT1 and LT2 performance builds. Its profile features 219°/233° duration at .050", .643"/.655" valve lift with a 1.80:1 rocker ratio, and a 118° lobe separation angle.

This camshaft features an 11% fuel pump lobe with 6.5mm fuel lobe lift. A 4° VVT limiter or full lockout is recommended. Fuel pump preload must be checked during installation on all applications, with particular attention to LT2 builds.

Katech's camshaft development draws on decades of racing engine experience and Optron Spin Cell valve motion analysis. Final power, driveability, and operating range depend on the complete engine combination, supporting components, and ECU calibration.
