Don't feel too bad I think I ran across your mechanic. I took my car to him knowing he charged $40/hr and he was supposed to adjust my rocker arms, his estimate two hours. But he couldn't get to it the day I brought it. Long story short it cost me $477.09 for this adjustment and a new set of lifters which I bought and the adjustment never happened. I went and got my car with my engine in pieces after he called me with the bill and wanted to know what I wanted him to do. He told me to complete the job it would cost somewhere in the neighbohood of $800. But hey I got all kinds of info on his ability to build and tune a BB Ford.
