Brian Tooley Racing CM32338206 Stage 1 PDS Blower Camshaft Kit for Chevrolet LS 6.2LThis is a great camshaft for those wanting the power production of the Stg II camshaft, yet desire slightly better driving manners. Will work great with any positive displacement supercharger on a 6. 2 liter engine. With 10 degrees of overlap it has a nice, mellow idle, but makes the power of much larger cams. This cam has more traditional intake valve closing and exhaust valve opening events, and conservative lift which makes this cam more durable
