[QUOTE="HoLeChit, post: 3615478, member: 35036"] From what I have read, I have found that: Stock 4.2+t5 tranny: 565lbs 4bt-750-800lbs+163lbs for NV4500. So we’re looking at adding 400lbs putting the 4BT combo in. From what I have read I can upgrade the turbo, intake, intercooler, and turn up the fuel a little and be sitting at 200 reliable horsepower and tons of torque, while looking at a top speed in the upper 70s and getting 25-35mpg. I just don’t see that happening with any other power plant, at least gasoline powered. The 6bt to my understanding is too long to fit, and adds a ton more weight. I can also rebuild the Cummins easily and with confidence, with the tools I already have. The simplicity of the swap is appealing too. Linkage, hydro boost, and a fuel shutoff wire, as opposed to a computer and stuff with a vortec 4.3 or something like that. A 350 would just be less power, more noise, and less fuel economy Yeah, there’s a significant weight increase there. Prior to leaving the trade, diesels were life for me too. I don’t know squat about carbs or distributors really. I am concerned about price, those used 4BTs are going for performance crate motor prices. But I figure if I could find a deal on one, it might be worth it. I do like the jeep i6 motors, and would definitely keep it in the truck til it died, but the thought of an efficient diesel in there keeps getting stuck in my head. [/QUOTE]
