Reply to "Engine rebuild"

It depends on the core the cam is ground on. I have a -9 from Comp Cams which requires a bronze gear.

I inspected my gear after the build / dyno run, also after ~2,000 miles and it was showing no wear. I am at ~ 3,500 on the gear and no problems so far.
I do run a high volume oil pump. A quick and dirty way for me to check wear would be to see if the ignition timing has altered with a timing light, maybe I should check some time..
If you can use a melonite gear that is certainly the best way but using the wrong gear can also ruin the gear on the camshaft which is an expensive and more complicated replacement. Plus all the metal fragments created.
