Superbirds could be ordered with a 426 Hemi, 440 Super Commando or 440 Super Commando with three two-barrel carb V-8s and with four-speed manual or automatic transmissions. Broughton’s is one of 716 built with the 440 and three Holley carbs. It makes a seriously understated 390 hp and 490 lb-ft of torque. Zero to 60 mph takes 5.9 seconds.
