BTR POSITIVE DISPLACEMENT SUPERCHARGED (ROOTS STYLE) STAGE 3
BTR POSITIVE DISPLACEMENT STAGE 3
231/248 .617″/.595″ 120+5
This cam is on the upper end of aggressiveness for GM LSA and LS9 engines. Will work great with any positive displacement supercharger on a 6.2 liter engine. With almost 0 degrees of overlap it has a definite camshaft sound, but still has a mild idle, yet makes the power of much larger cams. The secret is in minimizing the overlap, while maximizing the intake valve closing and exhaust valve opening events. This cam has proven to make more power than other cams that have more lift, which makes this cam much more durable. Cam specs are 231/248 .617″/.595″ 120+5 and comes a 3 bolt timing gear pattern. This cam was used by Redline Motorsports to set the Camaro ZL1 cam only record!
Lift approaching .650″ or more while using stock 15 degree rocker arms with too much open spring pressure can damage valve tips long term. We recommend maximum lift of .630″ and maximum open pressure of 400 lbs when using stock rocker arms.
