LS Hot Rod Cam

The LS Hot Rod Cam from Brian Tooley Racing is a high-performance hydraulic roller camshaft engineered for LS-series engine builds demanding aggressive power delivery and extended RPM capability. Designed for enthusiasts and professionals building race-ready or high-output street engines, this camshaft transforms the fundamental breathing characteristics of GM's legendary LS platform, enabling significant gains in peak horsepower and torque across the mid-to-high RPM band. Whether you're constructing a drag-strip competitor or a street rod with serious attitude, the LS Hot Rod Cam delivers the valve timing and lift geometry required to maximize fuel charge velocity and combustion efficiency.

This camshaft features a 0.619-inch intake valve lift and 0.607-inch exhaust lift with a 217-degree intake duration specification and a 114-degree lobe separation angle (LSA), positioning the cam in the aggressive spectrum ideal for high-RPM applications. The hydraulic roller design ensures reduced friction, improved durability, and lower maintenance compared to flat-tappet alternatives, while the 1750 to 7100 RPM power band demonstrates a broad powerband suitable for both street manners and track performance. Brian Tooley Racing's precision manufacturing and quality control guarantee consistent valve timing and lift across the entire rev range, critical factors in preventing detonation, optimizing scavenging, and protecting engine internals during full-throttle operation.

Builders and engine shops integrating the LS Hot Rod Cam should confirm compatible valvetrain components, including pushrods, rocker arms, and valve springs rated for the aggressive lift and duration profile. Installation requires proper valve lash adjustment and timing verification to ensure optimal performance and longevity; professional engine builders familiar with LS-series geometry will recognize this cam as an excellent match for naturally aspirated and modest boost applications seeking reliable mid-range punch and upper-RPM responsiveness. Weighing 10.36 pounds and measuring 22 inches in length, the LS Hot Rod Cam integrates seamlessly into standard LS block installations and pairs effectively with upgraded fuel systems, ignition timing, and intake manifolds to unlock the full potential of your engine platform.
