Bristol chose Chrysler V8 engine in 1961 when the Bristol 2-litre needed replacing. In fact the 313 cu.in. 5,130cc engine was a Canadian engine more likely to be found in Plymouth or Dodge cars than Chryslers. It was a cheaper A-type engine than those fitted to Chrysler or Desoto cars. In 1969 the Bristol 411 was given the much larger and better 383 cu.in. 6,277cc V8 'Wedge' engine which found its way into a number of Chrysler performance cars. From 1976 Bristol chose to use smaller Chrysler V8 engines for reasons of economy and emmissions.
