Tick Performance proudly offers our Elite Series of Camshafts designed specifically for LS1 & LS6 Engines! Using the latest and greatest technology available, we've put together a complete line of Camshafts that are designed to meet every goal, from mild to wild. Our Elite Series of Camshafts are all manufactured by Cam Motion and are updated with a new version every time an advancement in valvetrain technology becomes available, so they're ALWAYS cutting-edge! Although we suggest measuring for piston-to-valve clearance during ANY camshaft install, every Elite Series Camshaft is designed to fit in a stock engine & stock heads with adequate clearance unless otherwise noted. These cams are designed to maximize power, reliability and valvetrain longevity.

You won't notice much of a difference in idle, but you'll notice a big improvement when you jump on the throttle! We strongly suggest the use of our Tick/PAC Dual Valvesprings and hardened pushrods with this camshaft (sold separately.) Hundreds of hours were spent developing this camshaft to perform precisely the way we advertise, so as a result, changes to the LSA or any other specification of this camshaft are not available.
