Road Runner

The 1970 Road Runner arrived with new front and rear looks. Updates included a new grille, leather seats, hood, front fenders, quarter panels, single-piston Kelsey-Hayes disc brakes, and even non-functional scoops in the rear quarters.

The Air Grabber option was redesigned to increase efficiency to better intimidate opponents. A switch below the dash initiated a vacuum servo to slowly raise the forward-facing scoop exposing shark-like teeth on either side.

A heavy-duty 3-speed manual became the standard transmission making the 4-speed and Torquflite auto options.

This was only the second, and final, year for convertibles, but are actually more sought-after because of a better dash, high-impact colors, and more options like high-back bucket seats.

The 440 Six Barrel option returned but with a factory recalled cast iron intake that were supposed to be replaced with the more desirable Edelbrock intake from the previous year.

Sales dropped dramatically, but still outpaced the GTO in production, but came up short against the Chevell SS 396. Sales took a beating because of insurance premiums and stiff competition from the ancestor Duster 340 that performed as well and was eligible for cheaper insurance.
