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.
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 converter is necessary for automatic transmission applications.
