The Chrysler Valiant holds a special place in Australian motoring history, and one of the most common debates among enthusiasts is: six-cylinder or V8? With options ranging from the torquey Hemi Six to the burly 318 and 360 V8s, choosing the right engine can define your driving experience, maintenance costs, and collector appeal.
Here’s a detailed comparison of six-cylinder vs V8 Valiants, designed for enthusiasts, daily drivers, and collectors alike.
1. Engine Options in the Valiant
