We love COMP’s billet timing set. Beyond robust parts that look and feel great, these double-roller timing sets make it super easy to degree the cam. Pull the lower gear off and select the crank keyway with the desired amount of advance or retard in cam timing, then line up the appropriate gear tooth with the dot on the cam gear. The roller cam requires a thrust button. McAfee will check cam endplay and adjust this against the COMP Cams two-piece timing cover before final assembly.
