Valve seat grinder

Check Craigslist.

I got the B&D valve grinder and a Sioux seat grinder with a bunch of stones. All for $200 I think it was.
The guy said I was the only one out of about 6 people that called him to show up. He had it listed on Craigslist for a couple of months. He had been using it to do Chevy stock car motors so the stones that came with it were perfect for Mopars.
