Also, oiling issues aren't the cause of your cam gear being eaten up (you can thank the crappy hardened steel gear on your HEI for that). You didn't mention what engine you've got but I assume its a V8 if you can replace the gear and not the cam. Regardless, the stock oiling system of either the V8 or I6 engine is adequate for keeping internals lubed properly. I have heard of oiling issues in the AMC V8's but not with any regularity and not when pertaining to non-racing appplications. IMO, replace the gears and don't worry about it.
