Im lookin at a 97 PSD reg cab f350 with 140000 miles auto 4x4. he wants 12,500 obo i think its worth bout 10k to 11k. If i sell my 02 for this truck. How hard and expensive will it be to get 400hp. Set aside the tranny cuz i know at least a rebild kit. Iwas just wonderin about the engine and how much it will hold stock before i have to put rods all those things.
