However, generally speaking, a 1977 Chrysler 440 would have been in the range of 225-230 horsepower and 370-380 lb-ft of torque. Keep in mind that these are net horsepower figures, reflecting the power measured at the crankshaft after accessories are considered, as mandated by SAE standards of the time. Gross horsepower ratings, which were common before this, would have been considerably higher.
To get a precise number, you'd need to specify the exact model of vehicle the 440 was in (e.g., a Road Runner, a New Yorker, etc.) and possibly even its trim level as options could affect output slightly.
