I was already leaning towards the 6bt, Looks like thats the direction ill go. If I stay 97 and older I can get away without the smog for diesels. Although I have a friends who will make me a great deal on a motor and tranny including harness etc out of a wrecked 2005 ram 3500. Any thoughts on that year cummins? Im pretty familiart with the diesels up to about 2000.
