Comp Cams GM LS3/LS4 HV Series Camshaft - 54-273-11

This COMP Cams HV cam is designed for GM cathedral port 4.8L/5.3L/6.0L powered vehicles. It provides amazing drivability and throttle response while also requiring minimal tuning. Torque is increased across the entire operating range while still producing +79 horsepower at peak. Get the most out of your daily driver truck, SUV or 4x4 without sacrificing street manners. The HV cam will provide a deep rumble with a mild, yet noticeable lope. At .575" lift, this cam is designed to take advantage of the inexpensive 26906 valve spring upgrade. Also compatible with stock converters.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

Camshafts control the amount of time that your intake and exhaust valves are open. An increase in camshaft size will increase performance while also increasing how rough your vehicle's idle is.

For more than 35 years, the COMP Cams mission has never changed: to produce the highest-performing products possible, provide customers with superior service, and to lead the industry in technological development. While the COMP Performance Group has grown to multiple companies and hundreds of employees, we still retain the competitive spirit and desire to be the very best that has positioned COMP Cams as the absolute leader in valve train components.

COMP Cams has never forgotten that performance is defined by results –both at the track and on the street. We spend thousands of hours working with individuals, teams and companies to ensure that our products provide superior performance and reliability. Whether we’re working with a Pro Stock or Sprint Cup team, or putting thousands of grueling miles on one of our pro touring or street/strip components, we test our products in the same places you do. That’s why we know that every COMP Cams product will perform to the highest of standards.
