LS Red Hot Cam

The LS Red Hot Cam by Brian Tooley Racing is a high-performance hydraulic roller camshaft engineered for GM LS-series engine platforms. Built for enthusiasts and professionals who demand maximum power extraction from their LS powerplants, this camshaft delivers aggressive lift and extended intake duration characteristics that unlock additional horsepower and torque across the mid to upper RPM range. Whether you're building a street performance engine, race application, or upgrading an existing LS platform, the Red Hot Cam provides the mechanical foundation for measurable gains in engine response and overall output.

Featuring a 0.619-inch intake valve lift paired with a 0.617-inch exhaust lift, combined with a 221-degree intake duration and 113-degree lobe separation angle (LSA), the LS Red Hot Cam is optimized for mid-range to peak RPM performance. The hydraulic roller design eliminates the friction penalties of flat-tappet cams while providing superior longevity under sustained high-RPM operation. This specific lift and duration profile is calibrated to work within standard LS cylinder head flow characteristics, making it an ideal choice for bolt-on performance upgrades without requiring extensive head porting or fuel mapping changes on naturally aspirated applications.

Technicians and engine builders trust the LS Red Hot Cam for street, strip, and motorsport applications where reliable, repeatable performance is non-negotiable. This camshaft is supplied as a single unit and integrates seamlessly with factory LS valve train components, push rods, and lifter hardware. Proper installation requires accurate timing set procedures and verification of valve-to-piston clearance before engine startup, particularly in forced-induction or high-compression builds. Pairing this cam with quality fuel (91 octane minimum for naturally aspirated use) and a tuned intake and exhaust system will yield measurable improvements in throttle response and peak horsepower across the entire RPM band.
