Duel is a 1971 television (and later full-length theatrical) film starring DENNIS WEAVER, who plays a terrified motorist stalked on a remote and lonely road by the unseen driver of a mysterious TANKER TRUCK. It was written by RICHARD MATHESON  based on his own short story, and directed by STEVEN SPIEBERG, in his feature film directing debut.

Road Test magazine tested the 340 Demon (similar to the 340 Duster) in April 1971. They got from 0 to 60 in a quick 7.8 seconds - remember, this is with an automatic and bias-ply tires - and ran through the quarter mile in 14.6 seconds at 96 mph, with a top speed of 127 mpg. Gas mileage was at 14 city, 17 highway, not far from the standard 318 and reasonably close to the slant six. Cornering, finish, luggage, performance, steering were rated excellent; details, instruments, quietness, ride, visibility, overall were rated very good. The base price was $3400 including tach, stereo cassette, and automatic.
