All the Mopurists, don't look, it's blasphemous!

There's plenty of hellcat motors on ebay around 10k that would plug n play. Another 10k of mods and that LS would eat dirt.

Exactly why the guy used an LS. 20k for the hellcat engine and mods and you still need to buy and build a car so you'll have more then his 20k into the total car.
