I went for a cruise on Sat and was about 50 miles from home when I left a red light shifted up to third when I had a loud bang, backfire, and everything went dead. I checked for spark and found none. Pulled the distributor and sure enough three teeth were gone the remaining ones are worn at a angle whick looks like they are not making full contact with the cam gear.

I looked into the distrb hole and saw what looks like a circle worn into the block where the face of the gear rides.

A person brought down a new distrb and we got the car home but I wonder what caused the wear and how do you solve the problem. Maybe a shim to raise the gear to the correct height. What would have caused the wear in the first place?

It was an MSD billit distrb in a 460 crate motor.

Any help would be appreciated.

Thanks
