Brian Tooley BTR LS3 Stage 1 V2 Cam Kit 217/23X .615/.636 113 LSA + LS7 Lifters + Trunnion Upgrade + .660 Dual Springs + LS9 Gaskets – Fits LS3 L99 L76 L77 Camaro Corvette G8 GXP – +56HP

Description

The Brian Tooley Racing BTR LS3 Stage 1 V2 delivers dyno-proven gains of 56+ rear wheel horsepower and 24+ lb-ft of torque with a smooth broad power curve that pulls strong from the bottom of the RPM range all the way to redline — the ideal upgrade for Camaro SS, Corvette C6, and G8 GXP daily drivers and weekend warriors who want real performance without compromise. Featuring 217/23X duration at .050″, .615″/.636″ asymmetric valve lift, and 113 LSA, the LS3 Stage 1 V2 delivers more power and torque across the entire RPM range with a smooth predictable power curve that never catches you off guard — engineered to work with factory torque converters and maintain excellent street manners. BTR camshafts are designed in house, Spintron tested, and engine dyno proven before they ever reach a customer — each cam born from its own specific cam core with no generic cores used — resulting in more average torque, higher peak power, and maximum depth heat treatment for long-term reliability. This complete kit includes everything a professional installer would spec — BTR LS3 Stage 1 V2 camshaft, 16 premium LS7-style roller lifters with lifter trays, .660″ dual valve spring kit with steel retainers, hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness, premium valve stem seals, front timing cover gasket set, 2 LS9-style MLS head gaskets, and a premium LS rocker arm trunnion upgrade kit. One order, one shipment, zero guesswork. Lifetime warranty if installed by a certified machinist.

The 16 premium LS7-style roller lifters with lifter trays reduce friction, improve oiling and stability at high RPM, maintain correct cam and lifter contact patterns for longer life, and simplify break-in for reliable valvetrain performance under load — the first upgrade every serious LS3 builder makes on any Camaro SS cam swap, Corvette C6 performance build, or G8 GXP LS3 upgrade. The .660″ dual valve spring kit with steel retainers delivers the correct seat and open pressures needed for reliable high-RPM operation at the LS3 Stage 1 V2’s .615″/.636″ asymmetric lift level — the right spring package for this application without going overboard. The LS9-style MLS head gaskets are precision matched to the larger bore rectangle port cylinder heads found on the 6.2L LS3 — delivering superior crush resistance and long-term sealing reliability that composite gaskets simply cannot match. The premium LS rocker arm trunnion upgrade kit converts your stock LS3 rocker arms into captured roller bearing rocker arms — eliminating the factory failure point that has caused catastrophic engine damage in countless LS builds. Brian Tooley Racing camshafts are designed and manufactured in the USA — backed by extensive Spintron testing and in-house dyno development.

Built for 2008–2015 GM 6.0L and 6.2L LS-based engines including LS3, L99, L76, and L77. Fits Camaro SS, Corvette C6, Pontiac G8 GXP, and LS swap builds running these engine families. Works with factory torque converters — no stall upgrade needed. Fire it up and the BTR LS3 Stage 1 V2 wakes up your 6.2L with a noticeable cam note that separates it from every stock LS3 on the road — throttle response is sharper, the pull is stronger, and the power is broad and consistent from the first RPM to the last. Big power. Broad powerband. Built for the street.
