BTR Gen III & IV LS Truck Norris Camshaft

Brian Tooley Racing Truck Norris camshaft supplied through Harrop for Gen III / Gen IV LS truck and swap applications.

This camshaft is aimed at strong street torque and a pronounced performance idle while retaining compatibility with appropriately prepared LS valvetrain combinations.

Valve springs, pushrod length, piston-to-valve clearance, converter/gearing and ECU calibration must be checked for the final engine combination.
