Heres a link to the auction I have. I'm selling one of the two C-304-8-B cams that I had Clay Smith Engineering build for me a few months back. I ordered two for two separate projects. I completed one of the two 454's I had with one of the C-304-8-B cams and holy smoke do these things make an engine run like a mad man. However, my second project is not going to happen so I have one left over. These cams make your engine sounds mean as hell too. Check it out.
Please note: More boat races have been won with this cam than any other. That's what George Striegel told me himself when I purchased these. Check out the auction.
