Red Shift 468 Cams are the bolt-in kit for 107, 114 and 117" Milwaukee-Eight® engines. The 468 delivers significant improvements in power and throttle response right where you ride. The Red Shift 468 is designed to compliment the 4-valve heads' high intake flow while its unique design overcomes the restrictive exhaust port for big gains in both torque and horsepower. The 468 provides instant acceleration below 2,000 RPM while pulling strong to 6,000 – really shining in the 2,000-4,000 RPM cruising range. Cranking compression is unchanged for easy starting, and proprietary Red Shift Cams® ramp design delivers quiet operation and long valvetrain life. Works well with the factory Touring header pipe as well as aftermarket racing exhaust systems. This is THE Bolt-In Big Torque Cam for the Milwaukee-Eight® Engine!

Red Shift 472 Cams
are the bolt-in grind for 114, 117 & larger Hot Rod Milwaukee-Eight® engines. The Red Shift 472 is designed to work with factory valvetrain components, as well as modified heads with upgraded spring / valve combinations and porting. The Red Shift 472 is designed to be a mid-range to top-end cam, but its unique timing maintains low-end torque. The Red Shift 472 really shines in 114 inch and larger engines which are modified with slightly more compression and air demand. Designed to enhance the unique cylinder head layout of the Milwaukee-Eight® engine, the 472 is a great companion to the extremely successful 468 cam. The 472 provides a different ride experience -- if you like to stay in the throttle till red line, the 472 will get you there very quickly! Cranking compression is only slightly increase over factory for easy starting, and proprietary Red Shift Cams® ramp design delivers quiet operation and long valvetrain life.
