Hi, Guest
That's the old 5.9 Magnum eh? They're like the old 454SS was... boatloads of torque, not a lot of HP from the factory. They also don't rev very high if memory serves. I believe cams are your best option if you want to make a lot more power... a new coil and plugwires will make it a lot more responsive, too.
What rear end is in that thing?
EDIT - 250BHP on the stock 5.9L in the R/T, 345 lb/ft of torque. Stock power peaks around 4400 or so as you noticed. Yeah, cams for sure, new intake system and perhaps a proper dual exhaust? That'll get you right up there, along with a PCM flash for 91+ octane.
