Bare Bones Budget 400 Build

So, if you were going to re use a cam, would you clean it up the same way with 400 grit and oil??

I have an engine (318) and I replaced the cam bearings but decided to re use the cam. So I didn't want to put a used surface against a brand new bearing, so how should I clean up the cam or not.....

??

Can clean up your cam bearing surfaces on your cam with Crocus Cloth, it's a really fine grade of emery cloth. Really leaves a nice polished finish behind, use it with WD-40.
