Engine Data (compare years, see more 1981 performance information)

Gross Horsepower was measured using a blueprinted test engine running on a stand without accessories, mufflers, or emissions control devices. In 1971-2 automakers began to specify power in terms of SAE Net Horsepower (as defined by standard J1349). Net Horsepower is measured with the engine in "as-installed trim", with all accessories and standard intake and exhaust systems. This was done to reduce the advertised power for insurance rates and to account for different approaches to emission reduction equipment.
