The production Blackhawk used Pontiac Grand Prix hardware and Pontiac's 7.5 L (455 in³) V8 engine. Output from the specially tuned engine was 425 hp (317 kW) and 420 ft·lbf (570 N·m). A GM TH400 automatic transmission was used, allowing the 5000 lb (2300 kg) car to accelerate to in 8.4 seconds with a top speed. Fuel economy was just 8 miles per gallon (30 L/100 km). Later Blackhawks used Pontiac's 403 and 350.
Exner's design included a spare tire that protruded through the trunklid and separate headlights. The interior included gold plated trim and birdseye maple. All early Blackhawks were coupes, but rare sedans were produced later.
In 1980, the Blackhawk was redesigned for the Pontiac Bonneville chassis.
The first production car was purchased by Elvis Presley (who later bought four more), with other famous owners including Sammy Davis Jr., Evel Knievel, Robert Goulet, Larry Holmes, Willy Nelson, Dean Martin, Jerry Lewis, Lucille Ball, Wilson Pickett (1974), Billy Joel, Elton John, Paul McCartney, Al Pacino, Frank Sinatra, Joseph Denney, Wayne Newton, and H.B. Halicki. Frank Sinatra had vied with Elvis for the first car. Each car included a dash plaque naming its original owner. The price for 1972 was US$23,000 but spiked to US$43,000 the next year. About 500 Blackhawks had been produced when production ended in 1987.
