yes the 6.4 can do 700 on stock apearing chargers....
You said "Stock appearing"... NOT stock. 6.4 bone stock turbo's won't do 700hp.
Cheetah's are stock appearing and have done 750hp in single pump work stock trucks. Stock DMax VNT's won't do much past 550-600 at the very best.
The problem with work stock is that most of the tech guys at pulls don't care to know that an actual stock dmax comp wheel has 11 blades etc etc. They'll look at the charger and say.. "that's stock, go ahead" or the same scenario could happen with a 6.4 with mod'd twins.
