On a side note, I dont really see anyone hot rodding the base model 09 - up Challengers . Seems to me that would be the easiest gen111 hot rod swap of all. Pick up nice clean body, add the hemi drivetrain and everything you need for hemi conversion from junkyard, go nuts on the engine, add sticky tires and other race stuff ( maybe RT stickers if you like). Should be way ahead on cost vs a base RT and much faster if done rite.
