New cam for build?

[Mile_high]

I've read tons of build threads and all I see being done with cams is keyways. Do you guys not find any worn lobes on cams you are pulling at 150,000+ miles? Has anyone looked into a used camshaft enough to find out what the wear reveals after substantial use?

If it's all good and I won't have to spend that several hundred bucks when the day comes, great...but this has left me puzzled. In the world of gassers and built sbc setups for pocket change, I would never put a used cam in a build because of wear.

personally i have never seen a cam with much wear at all. I did do a socal cam, looking back i probably should have used my stocker.

Reused my stocker with 198k on it. Still looked new.

Did you replace cam bearings? I thought GM spec said no no on replacement, which I can't wrap my head around.

Reused the stock bearings as well. I was amazed at how well the insides looked with the abuse I put it through.

The rollers help keep the wear down. Parts are built to last in extreme conditions, this is why diesel last so long. This aloud us to make lots of power with relative few aftermarket parts.
