Stanley Morton has a smaller shop. He is in Broken Arrow, OK, about half an hour drive. Patterson's dyno set up has eight wide bands, Stanley's does not. Depends on what I need to do. Patterson builds Stock, SS and Comp engines mostly. Stanly builds Pro Mod and Top Sportsman stuff, also the best crank shaft guy I know.
Known both Stanley Morton and Allan Patterson for about forty years. They both also do machine work for me.
