Potvin Racing Cams 1948 Mug

With the post-war auto racing boom in full swing, the custom ignition business Chuck Potvin started in high school quickly outgrew his parent's garage. In 1948 Chuck purchased a corner shop and decked it out with cam grinders, a homemade master cam generator, a dynamometer, and several lathes and began crafting his own cam grinds that, like his ignition systems, found a sweet spot in the market. While he made countless models over the years, the most popular was the 425 Eliminator, the cam that the first car to break the 160 mph barrier was running.
