BTR NA 3 Camshafts, LS Applications

BTR STAGE 1 V2 CAMSHAFT- This V2 version of our Stage 1 camshaft makes more power and torque everywhere in the curve compared to our legendary LS3 cams. Developed in house, we went back to the drawing board to find even more power and torque. These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards. 217/23X, .615/.636, 113 LSA

BTR STAGE 3 V2 CAMSHAFT-Developed and ground in-house using state of the art BTR designed lobes, the new LS3 Stage 3 V2 cam is the latest offering in the LS3 line up. This camshaft has an aggressive idle, and works well in the mid to upper rpm range with a 70 horsepower gain at peak. This camshaft will not require any flycutting of pistons with OEM LS3 combustion chamber size. If you mill your heads, it is always advised to check piston-to-valve clearance. An aftermarket stall is necessary to help  unlock this camshaft's full potential. 227/24X .636"/.636" 111.5 LSA

BTR STAGE 4 V2 CAMSHAFT- The V2 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 worth of night night juice. For proper piston-to-valve clearance, you cannot mill your cylinder heads without the possibility of needing to flycut your pistons. An aftermarket converter is a necessity for automatic applications. 233/24X .636"/.636" 111 LSA

BTR STAGE 5 V2 CAMSHAFT- Introducing the new LS3 Stage 5 cam from BTR. Developed in-house using BTR designed lobes, the new Stage 5 cam is the latest offering in the LS3 line up which has culminated from extensive in-house Spintron testing, coupled with thorough vetting on our Superflow Engine Dynamometer. This cam is not for the weak at heart. Intended for use as a MAX EFFORT NA style cam, in combination with ported cylinder heads, while also using an aftermarket throttle body and intake manifold such as our Trinity series intake. Best results when using a 5" cold air intake tube set up. If you're wanting brutal mid range and top end power, these are this camshaft's shining attributes. We've seen power figures North of 600hp on our engine dyno in a SBE application when used in conjunction with BTR valve train components and a short runner intake manifold. Higher than stock stall converter and lower gearing* (when applicable) is recommended along with an E85 compatible fuel system. This cam requires fly-cutting when using OEM pistons, but the extra labor is key to obtaining maximum performance from this combination. However, fly-cutting is NOT required on a L99 engine with exhaust notches. NOTE: To take advantage of this grind, it is imperative to use good flowing induction system along with added compression ratio. 235/25X, .646"/.646", 111 LSA

BTR RED HOT CAMSHAFT- BTR is proud to introduce our newest camshaft offering for 5.7, 6.0, and 6.2 LS engines. Affectionately dubbed The Red Hot Cam, we have put this camshaft in a wide variety of engine combos, and it was spicy enough to make excellent power in both boosted and N/A applications. Things really heated up once it was installed and running on the engine dyno. It showed excellent power gains over our existing Stage 2 PDS and LS3 Centrifugal cam profiles even with less intake duration. Using BTR lobes designed in house, this cam had just the right amount of kick that combined both great stability and durability during Spintron testing. Scoring a 1.5m SHU (Think Carolina Reaper and Pepper Spray) on the Scoville Scale, this cam is sure to add some heat to your build! 221/24X, .619/.617, 113 LSA

These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.
