Just wanted to give you a heads up.
My car died on Saturday and had to get towed home.
I found the 1/8" roll pin for the distributor gear had been sheared. It appears that this is a problem due to high volume
oil pumps. Mallory is going to 3/16" roll pins on there race distributors and list it also as a fix in there tech section. I pulled the distributor tonight, drilled it out and installed the 3/16" roll pin.
I hope this will help someone else, and keep them from being towed.
Thanks,
Ken M 2560
