Appreciate it I am posting this more in an attempt to help someone else not get stranded on the side of the road. As I posted on the last page I sheared my distributor gear last weekend at about the 1600 mile mark. The engine was built and dyno tuned by a Nascar engine builder. The performance has always been excellent. I did start to notice a little drop off in power the last few times I drove it before the failure(including the video footage) I had needed to turn up the idle due to low idle not long ago as well. It all ads up now. I hadn't timed the car in quite some time. With the distributor gear wear I bet I lost 5-10 degrees of timing. Anyway....after doing my research and reviewing my engine file I determined that my billet hydraulic roller cam had a pressed on cast iron distributor gear. That is a great thing, but the engine builder used a bronze gear.

It's basically an aluminized brass gear made for billet steel cams without a pressed on cast gear. It's also used frequently by the drag guys. It's absolutely not meant for the street especially on a cast gear.

This is the correct gear for my application. It's a GM melonized cast iron distributor gear. It should give me the reliability we all need for the street. It comes on most GM hei's and so forth.

I cut open my last two oil filters and strangly enough the last one had very little debris where the one before had a decent amount of brass. It looks like the oil filter did a great job of catching the wear. I had changed it 4 times in the 1600 miles.
