This is the blower cam listing for some specs we use for street cars and street – race cars builds. Generally the smaller blowers will require smaller cams, but the bigger blowers don’t necessarily require bigger cams. Smooth cam lobe design provides quiet valve train operation and excellent upper rpm stability. Three bolt heavy duty 8620 aircraft quality steel cam cores ensure excellent durability for your build. We recommend using our custom grinding services for the higher end and race only type builds to help make sure the set up will achieve your goals.
