The other day I found a great deal on a '96 Dodge 2500 gasser, I'm going to swap a cummins into it either way, but I kinda want one of the old V8s, a 504,555, or 470. Does anyone out there have any info on these engines? specifically the weight and durability of them, I'm not worried about the size as they are smaller than a 3208 CAT and i've heard of those being put into pickups.
