started to assemble the 455 this weekend,pistons in,cam in,then onto the timing set i have a comp cam 3213 set which should fit,But it is 1/2 inch too short.the crank gear and the cam gear fit good,i put the crank gear on and slid it in till cam gear was touching the cam,center hole in cam gear is 1/2 inch low.Anyone else run into this,also nowhere on the set is there a comp cam mark ,i thought they stamped there name on every thing.
