Specifically developed to fulfill the needs of the growing drifting market, these camshafts combine strong powerbands with head-turning idle notes. This lineup has offerings to cover everything from daily drivers to full competition vehicles with large displacement strokers. Our optional spring and pushrod kit includes matching valvetrain components that provide reliability and strength for high RPM use. The lightweight Titanium Retainers combined with our .660" Dual Polished Springs provide excellent valve control while thick wall Chromoly pushrods provide stability. See our other listings for the complete cam kit. The Michigan Motorsports Drift Series Camshafts are designed to meet the demanding needs of drifting by providing instant power to light the tires up and maintain that power throughout the RPM range. These are the same camshafts that Zack Calvin is running in his Z06 Drift Vette and 5th generation Drift Camaro to keep the tires burning! @zack_calvin The Stage 2 LS3 is an ideal choice for daily driven combinations where drivability is high on the priority list, or for drivers who prefer a strong powerband in the lower-mid RPM ranges. The Stage 4 LS3 is designed to bring max effort performance and sound to the stock bottom end crowd. Those that want a nasty idle and strong power in the high RPM range will find this to be an ideal choice. Piston to valve clearance should be checked when using stock pistons, especially if any milling has been done to the head or block surfaces.
