Pro Stock DragRacing is a class of drag racing featuring 'Factory Hot-Rods'. The classcan be known as 'all motor,' as the cars cannot use artificial inductionsuch as turbocharging, supercharging, or nitrous oxide, and there arevery strict rules governing the modifications allowed to the enginesand the types of bodies used. The National Hot Rod Association Pro Stockclass emerged from the production-based Super Stock class in 1970 with amore liberal set of rules and an absence of handicaps. Rules initiallyfavoured big-block V8s but by 1972 had changed to favor small-blocks toreflect contemporary trends in the American auto industry. In 1982, theNHRA implemented a new engine formula that allowed the big-blocks toreturn, due to the popularity of the Mountain Motor IHRA Pro Stocks withunlimited displacement in the late 1970s. However, NHRA still limits thesize of the engine to no more than 500 cubic inches(about 8100 cubiccentimetres) in displacement.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 80 pp. Englisch.
