Quick Answer. NASCAR stock cars were previously allowed 850 to 900 horsepower; however, this amount was reduced to 725 horsepower in 2015. The lower horsepower is used with a tapered spacer, which is used in the NASCAR Nationwide series. In addition, the 2015 rules include a reduction of 6 inches on the rear spoiler, which cuts down on the downforce for drivers.
In 1971, NASCAR phased in a rule to lower the maximum engine displacement from 429 cubic inches (7.0 liters) to its present 358 cubic inches (5.8 liters). NASCAR handicapped the larger engines with a carburetor restrictor plate. The transition was not complete until 1974.
