It was 1949 when the first roller cam was manufactured for the performance automotive engine, and it was Chet Herbert Cams who designed and ground it. Since then Chet Herbert Cams has been the leader in roller cams. Today's rollers feature faster ramp speed and higher lifts for the ultimate in power. Herbert roller cams are manufactured from the finest 8620 steel billet alloy steel bar stock. We've designed and produced cams for drag racing, oval track, road racing, boat racing, truck and tractor pulling, mud racing and even Bonneville land speed racing. Don't let the sticker on the side of the car fool you, many winning racers that run a Herbert Cam don't run a Herbert Cam sticker.
