I have a cam gear with a chain for checking clearance on the top oil galley area on SB Chevy blocks, which is often an issue. This was a previous Shop Solution. I also use it to check or set-up cam button to timing cover clearance for my engine builders or home assemblers. The gear is on an aluminum hub that fits into a core block without bearings, so nothing gets damaged. A BBC is next to build the same type checking tool.
