This camshaft will not require flycutting of pistons with the factory LS3 combustion chamber size; if the heads are milled, check piston-to-valve clearance. An aftermarket torque converter stall is necessary to unlock the camshaft's full potential, and installation requires BTR's .660 in Lift Platinum spring kit and hardened pushrods.
