The Hellcat V8 gets all the credit but do not forget the base for it is the Hemi V8 that has been with us for a while. This Dodge Challenger owner decided to beef up their own Hemi by doing a built motor stroker with 426 cubic inches or 7.0 liters of displacement.

It certainly pays dividends with this custom build showing 748 to the tires on 93 octane pump fuel:

That comfortably exceeds the Hellcat and is just shy of what a Demon makes on race gas. Which raises the question, what would this setup do on race gas and high boost?
