I was timing my car today and my distributor gear felt funny so I looked at it and the teeth look thinner then before, and there was also lines on the bottom of the teeth where it was thicker. I compaerd the gear to the gear on my mallory unilite and the unilite gears are thicker and have flat spots on the top of the teeth. The teeth on my dist now (stock ford) come to a point. What is going on? Should I be worried? Btw, cam is a comp solid lifter that is mabey 4 months old. Thanks, mike.

This problem was experienced by the GBM. He can explain the solution. DON"T DRIVE THE CAR TILL YOU FIX IT!
gp001, the distributor gear is just like the distributor, a stock ford replacement. I have no idea....to me it looks cast. If I had to make a guess, I would say cast iron but I could be wrong. The gear on my mallory unilite looks to be stronger then the stock ford one. However, I woul rather chew up the distributor gear then the cam. What should I do?
you need to get a cam gear that is compatible with the roller cam, period. the stock cast iron gear is not compatible with the steel roller cam, i would call comp and get a gear from them that is compatible with cam. as Dave said DO NOT DRIVE IT UNTIL IT IS FIXED!!!!!!!!!! you could end up causing internal engine damage from the pieces of the gear floating around in the engine

sorry mis-read your post i thought you said solid roller, ok i'm old and blind 
if that is case you have another problem somewhere, possibly the distributor shaft is slightly bent or your timing chain is worn out causing the cam to "rock" back and forth so to speak, for lack of a better term. it is also possible that the cam was hardened differently than it should have been creating an incompatibility with cast gear, kind of a stretch but it is possible. the best thing i can tell you is to call comp and see if the cam you have is supposed to use a special gear, IIRC some solid cams require a bronze gear

IIRC, bronze gears are for short-run motors-- i.e. strip only, not for street motors. They are very soft. Ask GP about bronze gears.....
hummer: sounds like you're still gonna need a new gear if yours is excessively worn-- pretty sure you need a cast iron gear. keep an eye on the new one. maybe your old one was just old or a bad unit?
