The KC model (from June 1977 to the end of 1978) series dropped the 2.0 and 3.5 engines, but retained the 4.0-litre. The 4.0-litre comprised a low-compression (7.6:1) Hemi engine which ran on standard-grade fuel and aided fuel economy, and a high-compression two-barrel (9.0:1) version of the Hemi for greater performance and towing ability. The KC also featured greater Australian content, using VDO gauges, a Valiant-style steering wheel, steering column and various other parts from the larger Australian Valiant lineup. The KC was offered in GL or upscale GLX trims, along with the addition of sports package options.
