Rapid distributor gear wear on roller cam 351

[juiceman]

when you use a roller cam which has a billet steel gear you need to use either a bronze gear or a billet steel dist. gear. assuming you got the right gear this time( billet steel) for 351w you will need to check the cam gear now. it is important to get the proper mesh on the gears. since you used the cast iron gear first you may have damaged the cam gear also. take a look at the cam gear to be sure everything is good. what is the wear pattern on the dist gear. is it a shiny wear mark that is smooth and fairly even, or is it a ripply grinded look on the teeth. the last could be indicative of a bad or worn cam gear or bad gear mesh. even with improper gear mesh the gears will last a long time. always remember to do your homework before you change parts, this way you dont have problems later.
