That didn't sit well with me either, the part about the builder being so secretive. Aren't you the guy who paid the tab? When I take my engines to the machine shop I specify exactly what I want done and he is my employee at that point, your situation is no different. Just doesn't make any sense to me. I would he at his door step with some very serious questions for this guy. Even if Keith Black built your engine he would tell you all the specs and parts used......this isn't voodoo!
