I'm running a locking collar on the distributor shaft to keep the bronze gear from climbing up the cam gear. It stabilized the contact interface and decreased the wear on it. It helped stabilize my timing too.

About 1500 miles on the motor and it still looks good. If I have to change it again, I will have the next one cryogenically treated too.
