The demand for this camshaft was in place before the first LS3 engine was torn down for a cam swap! With a history of making 470+ whp when accompanied by the proper bolt-ons, all while maintaining stock-like driving characteristics, this camshaft has found a permanent home on the shelves at BTR. Building on the easy integration of this grind, it should be noted that stock torque converters in G8 GT's, 5th Gen Camaro's, and C6 Corvettes work perfectly with this grind! However, if you're looking for an aggressive idle note, you won't be disappointed when you turn the key with this cam in control.

LOBES DESIGNED IN HOUSE BY BTR! The LS3 camshaft lineup was born from an assortment of custom grinds, dyno testing, daily driving, and real world experience.

Choose from Stage 2, Stage 3, or Stage 4
- Stage 2: 225/238 .620"/.605" 113+3
- Stage 3: 229/244 .630"/.615" 113+4
  - 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. We have seen 480 whp from this grind and supporting modifications (stock cylinder heads). If you add a set of good flowing cylinder heads to the mix, clearing the 500 horsepower mark is doable. If your application has an automatic transmission, you will need an aftermarket torque converter.
- Stage 4: 233/250 .630"/.615" 113+5
  - 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.
