Brian Tooley BTR N/A Stage 4 LS3 Camshaft
Specs: 233/250 .630"/.615" 113LSA
3 Bolt Pattern
The Stage 4 LS3 grind has been utilized on many max effort combinations with great success. We see 500+ whp with the addition of proper bolt-ons, while maintaining the durability you come to expect from BTR components. It is ground with nitrous in mind as well, working well with up to 300 horsepower of spray. For proper piston-to-valve clearance, you cannot mill your cylinder heads without the possibility of needing to flycut your pistons. A 3000+rpm converter is a necessity for automatic applications.
- VVT engines will require a VVT delete kit
- If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required.
Our kit options take the guesswork out and include:
Camshaft only: BTR LS3 Stage 4 camshaft by itself
Steel Retainer Spring Kit with Pushrods: BTR LS3 Stage 4 cam plus BTR Platinum .660" Dual Spring kit with Steel Retainers, Valve Seals, and 7.400" Chromoly Pushrods, 5/16" x .080" wall
