BTR CAMSHAFT LS1/LS2 N/A STAGE 4 33348123R0Specs: 233/248 .630?/.615? 111.5+2.5 The largest offering in our naturally aspirated LS1/LS2/LS6 lineup, the Stage 4 has proven its 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. In automatic cars, a higher RPM torque converter is a requirement. Consult your tuner regarding stall speed needs! Lobes designed in house by BTR!
