I have a cc503 I figured I would try and sell. the lobes are in great shape but someone tried to drill out the dowel pin and drilled it crooked so it needs re drilled straight. was told it has 5k on it and they were changing from short dowel to long dowel when they screwed the hole up. I was going to have it repaired but ended up using a bigger cam for my build. asking $100.00 shipped thanks
