Note: This year, General Motors changed the way that horsepower was measured. HP was now measured with net ratings (full accessories and exhaust included) as opposed to gross HP (engine power without accessories and exhaust hooked up). This had the effect of making it look as though horsepower had dropped significantly, even though it really hadn't changed much. Generally, net HP ratings are 20- to 30-percent less than gross HP ratings.
