Used Cams, Scratches?

[AnotherS197]

Hey guys, bought some used cams and looking for some input. Seller's been great with working with me. However I've noticed some scratches on three of the lobes that look like they were set down on the ground or something.

The seller says he didn't have any problems running them but I'm unsure about them. The scratches catch the finger nail a bit, but they are very shallow. Should I try polishing them a bit to take the "edge" off them? I'd like to run them, but don't want to risk my motor. What do you guys think?

Thanks. They're Hot Rods btw.

Being that they're on the lobe, I'd definitely have them polished out professionally if it were me. Also, make sure you clean the hell out of them before installing.

I've got a good machine shop about 2-2.5 hours from me, think that would be my best option to get them polished?

You could send them to www.deltacam.com

Your best option would be what Bruce said, but as home shop should be sufficient depending on the severity

Those would be easy to polish. Any machine shop can do it.

Thanks for the input guys. I think I'm going to go to the local speed shop I used to deliver parts to and ask for a recommendation on a machine shop. There has to be something local to me.

The seller offered me a 10 day return, but if I can just have the cams polished and be good as new I'll go that route.

A good light polishing shouldn't bring the cam out of spec, correct? I just want to make sure I'm not opening a whole new can of worms with email tunes tuning for what they're "supposed" to be.

No, and even then a few thousandths wouldn't make that much of a difference.
