WARNING: Cancer and Reproductive Harm www.P65Warnings.ca.gov

BLOX Racing Competition Series camshafts are designed and manufactured using BLOX Racing’s own chill-cast camshaft cores. The Competition Series cores are cast with wider primary and secondary lobes in order to provide better valvetrin stability at higher RPMs. Competition Series camshafts are a favorite with auto cross and road racers.

Competition Series HSL (High Speed Lift) camshafts are ideal for mild to highly modified street engine builds.  These are one of the BEST naturally-aspirated camshafts available!

Upgraded valvetrain is required.
