I finally found some one to check my block, never dreamed it would be this much trouble. I've called machine shops and engine builders within about a two hour radius from me with no luck. I finally talked to a guy in Nashville who gave the number of a guy, who gave the number of a guy that had one. He had a small one man machine shop but quit and went to work at a power plant and kept all his stuff. He's about an hour away and is going to check two blocks for me next week .
