I have a 1999 dodge ram 1500 2wd sc/lb v8 and I'm looking to put either a 4bt in it or a 12v. I know that with the 12v I can basically just drop the motor in the truck with minimal work besides beefing up the front end some snd the fuel mileage would be great in this size truck, I dont much about the 4bt so I need to know what would be the cheaper choice and better in the long run too, with the 4bt would I have to get all the wiring or would it match up with what the truck has now like the 12v would and would the extra fuel mileage of the 4bt be worth it or could I tune the 12v up to get the fuel mileage of the 4bt? So what would be the best choice?
