Drag racing camshafts suited to high rpm power. Designed for engines making 1400+hp using 75mm-83mm turbos. Requires KVS273-BT valve spring upgrade. NOTE: 7mm dowel pin supplied to limit Intake cam gear advance to 96° when using OEM piston designs. For best results, fly cut pistons for maximum stroke (Please check Piston to Valve clearance).
