Summit Racing™ Muscle Car Replacement Cam and Lifter Kits
Restore or recreate the legendary performance and sound of the muscle car era with Summit Racing™ MCR or Muscle Car Replacement camshafts. These are kits that provide the cam, lifters, and assembly lubricant in one package. Available in hydraulic or mechanical lifter designs, these cams mimic the specs of the originals—but are produced on today's CNC grinders using modern lobe technology to deliver better performance and reliability. Kits are available for a wide range of vehicles, including many Chevy small block and big block applications from the 1960s and up. Bring back the good ol' days and get that muscle car back on the road. Order the camshaft model recommended for your vehicle.
