^^+1 on what HemiLonestar said
i think the 6.1 is already in the new challenger

 

is this suppose to compete with the raptor or something?

 

Someone at Dodge has been listening to me on CAB. I've been screaming for a production 6.4L hemi forever.

 

Mopar released the 392, then a couple of aftermarket companies (Arrington and Indy to name a couple) went bigger. One offers a 426 3G hemi, the other a 440 3G hemi. I am gonna put a 6.1 stroker in my truck someday once I have the suspension and brakes sorted out (SRT-10 brakes going on soon once I get hubs and rotors).
