Question for new purchase!
 

I am looking into purchasing a 1994 silverado 3500 dually 4x4 with what was replaced with a 350... which is where my questions start as if its a good idea too have just a 350 in such a heavy truck, it runs a drives 4x4 works and i wouldnt be paying any cash, trading a four wheeler for it. Truck was inspected recently as well
