Chrysler Australia made the Valiant series. The best known is the Charger, built on the US Chrysler A-body platform (Plymouth Valiant, Dodge Dart etc)
but widened.
Very popular and still sells well to collectors. Pics are of the R/T model (early 1970's). Produced in 6 and 8 cylinder models.
The straight six 265 was the most popular. Scroll down to the last pic for this engine and why.
Ok. Below is the E49 engine. A straight six 265 ci. 302 horsepower due to hemi, different cam,
triple dual barrel carbs, and sports exhaust. These were faster from 0 to 60 than Ford or Holden (GM)
V8 offerings as well as easily beating them over 1/4 mile.
They had success in touring car racing and handled way better than the V8 models. At one stage 80%
of Valiant sales were Chargers.
This engine made the Charger the fastest six cylinder vehicle in the world for a while, only being eclipsed
by the flat six Porsche.
The Pacer sedan kept the speed mantle as the fastest four door six until 1988.
