Hemi Six Standard & Mild Crate Engines
Engine Information
  • The Hemi six engine started its life in the USA in 1965, when Chrysler Corporation decided it was time to replace the long lived Slant six engine with an upright and more powerful engine. Their main aim was to re-power the Dodge truck range.
  • By 1967-68 Chrysler had “shelved” the Hemi six in its final stages of development to continue on with the V8 engine.
  • In 1968 Chrysler Australia was looking also to replace the Slant 6 engine in its passenger cars, and Dodge truck range.
  • With their recent success in motor racing their interests were also in an engine that was easy to adapt into a Hi-performance engine for Bathurst 500.
  • Chrysler Australia set up and manufactured the Hemi six here in Australia. The 245 was fitted as standard equipment in the VG and one year later into the Dodge truck range.
  • The performance side was handled by Weber in Italy, thus the 265 was born.
  • Chrysler then reduced the 245 to a 215, but this motor was short lived and only lasted up till 1976.
  • Back in the states the Slant 6 lived another 12 odd years.
  • The Hemi six has been praised as one of the best six cylinder engines ever made.
  • The early Chrysler Jeep was powered by a 4 litre Hi-output six much like our Hemi.
