I dont think the heads will be the issue as you can make them work with the right cam. Did you get a wear pattern on the gear during install? Also I assume you are running a cam button.. Couple other things.. When you pull the cam look at the gear. Does it have any burrs or sharp edges? That'll eat one up too. Also have you tried a slip collar distributor? Just curious if the block and/or intake stack up could be off and causing the gear failure.. Just throwing out ideas.. Its a really sweet ride and looks amazing.

I cannot remember the size of the chambers Darrell. I'd have to look it up. The compression measured out to a calculated 10.6:1.

The pattern on the gear is good. It has a button in the timing cover and the &quot;walk&quot; was measured when it was built. It looks like there are more options that I did not know about (cam cores and distributor gears) when I wrote that reply. I can get a better core from Comp that will work with a melonized distributor gear. That should solve everything.

The wear on the bronze gear is normal from what I am told. I just hate seeing all of that crap float in the oil.
