1st Gen Crew Cab Engine
Once you go black you'll never go back. I have 4 cummins a gen 1, Gen 2, and two Common rails. I had some pretty radical gas trucks even with Dyers blowers. I won't ever own another gas truck they are usless to me for what I use a truck for.
The major question is do you have the whole Diesel truck or just the motor. You need the Truck. There is a lot more to a Diesel truck then just the motor. And you will need those parts.
I have two 05 common rail trucks. both Mercedes Six speeds. The 3500 short bed single is unbelievable. It has a programer ,exhaust and Fass lifter pump. Its like driving a 69 4spd. R/T. The mercedes trans shifts like a car so you can pull gears. And the power is chest planting. I just sent my son to Texas to drive another 05 home. 05 and 06 Reverse over and down to the left those are my favorate.
I just sold a cummins build wish I would have kept it. I started with a 87 gas truck blown small block. Here are some picks.
