? about MSD pro-billet dist.

I was told that i should change the distributor gear to a bronze gear instead of using the billet gear that's on the distributor. Because the billet one will chew up the camshaft gear in time, if i change to the bronze gear then it won't chew up the cam gear. is this just a myth or does this really happen? I was told by a fairly reputable mechanic but he also told me this information based on what he's researched about high performance chevy motors. Could this just be a chevy problem or for ford too? I don't really want to spend 40 bucks on a new distributor gear but if it'll save the camshaft gear then ok.

What distributor gear to use depnds on what camshaft you are using. The materials hardness of each needs to match. So the question posed is what camshaft are you using?
