This week we round off the Big 3 with a Chrysler HEMI. So-called because of its Hemispherical combustion chamber, this engine has powered pretty much every fast Dodge you can think of, but this particular one is the 6.4-litre unit, the latest version which first featured in the updated Dodge Challenger SRT8 392 ("392" because 6.4 litres is 392 cubic inches). Fitting really, as the 6.4 is an updated 6.1. Featuring such features of the modern age as variable valve timing and usage of lightweight aluminium, the HEMI 392 will also sit in the future Dodge Charger SRT8 and Chrysler 300-SRT8.
Interestingly, these engines also have a system on them that stops operating four of the cylinders during slow driving to save fuel. Handy considering the sort of cars it'll be found in.
