BTR Stage 4 Naturally Aspirated Camshaft For LS3 Engines - Single Bolt 

BTR camshafts are engineered for outstanding performance and drivability. Brian Tooley Racing provides a wide range of camshafts and configurations tailored for various truck and car applications. Whether your project involves turbocharged, supercharged, or naturally aspirated setups, BTR offers numerous grind options, all supported by years of expertise, knowledge, and a dedication to power.

Word on the street is that your stock LS3 just isn't doing it for you like you used to. Things are getting stale and you need to do something before you feel like parting ways with your dear friend. Luckily, BTR has just what you need to rekindle your love. This cam has made over 500 whp in cam only applications. I'm gonna say that again. 500 whp with a good intake, a set of longtubes, and an efficient exhaust. This is designed as a maximum effort camshaft while maintaining acceptable piston to valve clearance with unmilled heads. With its conservative lift, it is easy on valve springs and valve tips to ensure a long service life on your valvetrain components.

Note: Lift approaching .650" or more while using stock 15-degree rocker arms with too much open spring pressure can damage valve tips long term. We recommend maximum lift of .630" and maximum open pressure of 400 lbs when using stock rocker arms.
