Truer words were never spoken.

It's amazing how many people think tuning an engine means changing plugs and wires.
I had a customer who had a good running brakcet car. He decided to purchase an advance re-curving kit and install it. He called me and told me his car had mysteriously slowed 6 tenths in the quarter. He ended up doing leakdown tests, pulling the carb apart, changing plugs, lashing valves, etc., doing everything he could possibly think of because he didn't/couldn't believe that the distributor modifications he made had caused the car to slow. After he found nothing, I advised him to put his distributor back to the way it was. The next week, it ran within hundreths of the time he ran before recurving the distributor. The only thing he said was "It pulled harder after re-curving it. I can't understand it". The clock didn't lie, but the "butt dyno" did.
