Some food for thought on distributor gears. I've had several aftermarket HEI distributors sent here that showed HEAVY wear on the distributor gear after very short time in service. Enough that it needs to be mentioned here. I get in factory points and HEI's all the time and it's rare to see any wear on their nearly half a Century old gears at all, or at least not enough to be alarming or where they would need replaced.
These aftermarket HEI's are obviously "offshore" parts. The distributor gears are dark black bearing the resemblance of Chinese materials. The most recent one I had in here was for an Oldsmobile, purchased new from Summit Racing. The owner may have said it was a Pro-Line, but not sure. Really doesn't matter, folks just need to know that there is potential for quick wear and failure of those parts........Cliff
