New Product Brian Tooley Racing Gen III HEMI Cams for NA and Supercharged Combinations

Posted By: Event Coverage Team
There is no doubt the Gen III HEMI has exploded in popularity over the last several years and the NMCA Muscle Car Nationals credits it as one of its quickest growing segments. Brian Tooley Racing (BTR) has dominated the LS market with its camshafts as well as its complete induction package systems and it was only natural for the company to expand into the late-model HEMI market. The BTR crew has split the camshafts up into Stage 1 and Stage 2 offerings for each segment Naturally Aspirated, Centrifugal Supercharged, and Positive Displacement Supercharged. A Cam Phaser Limiter Kit is also available along with an assortment of OEM replacement parts. BTR has also designed conical valvesprings and custom locators to be used with factory OEM retainers. Stiffer valvesprings are also available while BTR will be releasing custom pushrods in the coming months. Listed below are cam specs for each stage and application: Naturally Aspirated Stage 1 with VVT P/N 242028133 Lift: 590-inch (intake) and .580-inch (exhaust), Duration at .050-inch 220/228-degrees, and 113-degree lobe separation Stage 2 with VVT P/N 242636122 Lift: .615-inch (intake) and .600-inch (exhaust), Duration at .050-inch 226/236-degrees, and 112.5-degrees lobe separation Centrifugal Supercharger Stage 1 for applications with 8-16 psi of boost like with a ProCharger D1/P1, can be ground on VVT or non-VVT cores Call for Specs Stage 2 for applications 16+ psi of boost like with a ProCharger F1X, can be ground on VVT or non-VVT cores Call for Specs Positive Displacement Superchargers Stage 1 with VVT P/N 242340195 Lift: .610-inch (intake) and .600-inch (exhaust), Duration at .050-inch 223/240-degrees, and 119-degree lobe separation Stage 2 with VVT P/N 243148184 Lift: .590-inch (intake) and .580-inch (exhaust), Duration at .050-inch 231/248-degrees, and 118-degrees of lobe separation For more information about Gen III HEMI camshafts and other valvetrain upgrades from Brian Tooely Racing, visit
