The 1968 models

                                                         In 1968, the Plymouth line was easy to remember as A, B, C. That is, A-bodies (Valiant and Barracuda), B-bodies (GTX, Satellite, Road Runner, Belvedere), and C-bodies (Fury, VIP).

1968 was one the best ever years for engines, with the small, light, and powerful 340 providing serious go-power for the Barracuda Formula S and a full range of big blocks culminating in the Hemi. At the low end, the 170 slant six brought good gas mileage and the entry-level 273 V8 moved the Valiant and Barracuda quickly with light weight and a light touch at the gas pump.
