If I remove the stock shim then its good, but I cant run the distributor with out that shim.....What should the shaft end play be set at for a minimum. I ended up puting the stock gear back on and orderd a brand new merc gear to put on this weekend. How come my old motor which was a 330hp 454 with a roller cam can run the stock Thunderbolt V merc gear and the 502 gm base can't. Is the 330hp cam non magnum roller cam not a one piece billet like the 502 cam.?? :)

Obviously, a used gear possibly can live on a new cam. Plenty people have done it. However, I can not tell you how many I have seen them wipe out the gear in 2 hours or less. It has happened to me as well in the past. I could maybe attribute others to someone doing something wrong, but I know I didn't do anything wrong. I loaded them up with the same Moly lube I always use on new gears, and they still got wiped out. Learned it the hard way. You may be able to get away with it, but I will never take that chance again. It is not worth having to take an engine apart over a $50 gear.
