T&D Machine is one company that prides themselves on creating some of the most radical rocker arm systems, including rockers for Pro Mod drag racers and NASCAR “Cup” engines.

However, high-ratio rockers increase the velocity of the valve, which can decrease the life of valveguides and they can also complicate getting the geometry correct. View Related Article
