Distributor Gear Sheared Teeth

[Chad E532]

Well yesterday was the first trip out with my newly freshened engine. During the rebuild I noticed some wear on the MSD bronze distributor gear I was running so I opted to try the Comp Cams composite gear that claimed longer life.
Pulled into the water box after and just started to get the tires spinning and the engine just quit, pushed it back and got a tow back to my trailer. Pulled the distributor out to find only 4 teeth left on it and the missing ones are sheared off right at the base of the tooth. In my early failure analysis I can only see two possible ways for the gear to lose it's teeth. First would be for the oil pump to lock up or to spin over hard enough to create more loading than the gear could handle and the other would be for some interference between the cap and rotor. When I got home I was able to turn the oil pump fine by hand with my pump primer setup and the cap and rotor look fine.
The only thing I can think of is that these gears will not work with high volume/pressure pumps like the HV55 that I am running. Needless to say I am going back to bronze after I pull the engine back out and find all the missing teeth in the oil pan.
Anyone else had problems with these composite gears?
Thanks,
Chad
