Curious... How did you overcome the cooling fan issue? I'm putting an '07 Charger 5.7 into my '50 Dodge Panel Van right now and am using all factory wiring modules in an effort to retain ABS, Cruise, etc. (with the exception of the airbags). I'm using a Northern radiator meant for a '57 Chevy (because it fits my space requirements) along with the dual fan setup meant for that radiator. Worst case scenario, I'll swap the Northern fans out for the stock Chrysler fans from the Charger radiator which I still have. Honestly, and please excuse my ignorance here, I don't even know if I'll have the same issue because I don't know whether the Charger uses PWM fan motors. I just haven't gotten that far yet.
