BTR CAMSHAFT - LS1/LS2 - N/A STAGE 4 - 33348123R0
Specs: 233/248 .630"/.615" 111.5+2.5
INTAKE LOBE LIFT @ TDC: 0.06269
The largest offering in our naturally aspirated LS1/LS2/LS6 lineup, the Stage 4 has proven it's worth time and time again. The Stage 4 sacrifices a some low rpm torque while on a mission to make max peak power. It is not uncommon to see 460+whp with proper supporting mods including a quality set of cylinder heads.
ANY cylinder head milling with the use of factory pistons requires you to fly cut the valve pockets and check piston to valve clearance!
In automatic cars, a higher RPM torque converter is a requirement to help unlock this camshaft's full potential.
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.
Requires the use of our .660" Lift Platinum spring kit with titanium retainers and hardened pushrods.
