If you change the shape of the lobe by more then .0005" you could screw it up.
If the rust doesn't come off, I'll do you a favor and re-grind it for the shipping cost. I normally don't do things for free, but I don't like seeing people get screwed.

That being said, on something like a cam lobe, it would make me nervous to use any power tool to remove that rust. If it can't be removed by hand with either a rag and WD40 or penetrating oil, or even 1000 grit wet sanding, then I'd be looking to send it back.
anything that causes grooves or uneven surfaces to form on that cam will cause problems eventually.
my response earlier was meant to reflect on someones idea that "omg wire wheel wont take any metal off the cam lobes nooobs!".... I was more responding to someones attitude than anything else.
Thanks Camking. I will be in touch if this thing does not clean up. Hopefully soaking it in PB Blaster for a few hours will do the trick.

Inspect the lobes to see if material has good size pits.If not run the thing.These cores are plenty hard.If the journals dont clean up, I would run it to a local machine shop with a crank polisher or lathe and spin it. You could also try using scotch bright on the lobes as well. Roller camshafts dont wear unless the core is borderline soft. Then the rollers start to dig in. I see alot of posts here were guys shy away from used cams and say it has this amount of miles. New or used if it has good lobes it'll run. If not sent me all those old bones! I'll grind um

Look forget the WIRE WHEEL idea, soak that thing in some wd-40 or some fuel or card cleaner, wipe it down with a rag and see what comes loose and what sticks, then take it to a shop if it needs more work.....
Just thought I would give you guys an update on this situation. I tried to clean it up with PB Blaster, even let it soak for a good 4-5 hours and it did not really help, it is rusted to deep. I received an email back from Thunder Racing and after they saw the pics they advised it would most likely have to be reground.
I have 2 questions. Should I just purchase a new cam and be done with this? Or should I have it reground. If so how much does it cost to regrind a cam? **** like this makes me think I should have just bought the 03 Cobra I originally wanted.

Take it to your local machine shop and have them put it in the crank polisher with a "soft" belt, and let it rip. It won't eat material and will give you a micropolished finish just like a crank.
Good point. I just about **** myself after reading that. Definately made me laugh about the situation.

You can have the cam reground to different specs(bigger or smaller), but that may require a different pushrod length.
If you want I can regrind it when I'm doing a run of LS1 cams.
If you didn't want to change the pushrods, I could grind it to:
230/235 .578"/.600" 114lsa
If you don't mind changing the pushrod, I could grind it to:
230/235 .612"/.600" 114lsa
or
235/239 .600"/.580" 114lsa.

Have you contacted the guy you bought it from? Since his shitty packaging job wrecked the cam he should at least contribute some dough to making it right. Guy had to know the thing was messed up when he sold it to you.

You know, when I sell something I normally clean it up so it looks as good as it can when the buyer gets it. The seller could have cleaned it up for free. He obviously had the attitude that he has the money now and its your problem.
