Here's a few pictures of my Cummins powered Suburban.  It pulls like crazy and best of all, I'm getting 26 mpg on the highway.

Man, this is really cool. I've been thinking alot about doing this with my '87 R30. Did you have to modify the cross member under the engine? I saw you'd said that you'd modified the support under the blancer but I'm not picturing which support you modified. Thanks! Keep up the good work and good luck!

well i just thought i would let evryone know that was keeping and eye on this thread that it is no longer. I sold the truck as a roller yesterday...looking for a 4x4 now

[Pullin81]

well i bought another crew cab..you may remember the bagged crew cab dually i was building with the cummins...well i sold the truck and decided to go up instead of down....its an 1985 GMC K3500 welfare model...there isnt even an interior light in it...It has a running 350/4sp manual which is perfect for my cummins swap... the only problem that in a little sketchy on is the front drip rails here missing for how long i dont know.

Alot of the steel on the truck needs to be replaced but thats fine im not shooting for nut and bolt resto on this on its just onna look cool and be functional.

my plans are to go threw all the steel...cab corners, rockers, new doors, short box conversion, install a 8 inch lift and 37" tires, fab bumpers which i have a local guy in town doing for me that used to build alot of them...stick the 12V  in the truck with the 5 speed, and run a devorce transfer case ...

heres some pics from my phone the truck looks alot better in the pictures than it does in real life....its gonna be some work but it will be worth it in the end....i plan on doing every bit of work to this truck on my own with the exception of the bumpers cause it was a little trade deal we had.

Looks like a real good platform to start with.

If your going to do a 5 speed, just get one out of a 4x4 and you won't have to do the divorced transfer case.

i would go with a 4x4 unit...but i had the 2wd unit for my dually i was building that i sold that has never been used....

Allrighty, there is a guy in Illinois that rebuilds NP205 Divorced Transfer cases if you are looking for one. Google Moonshine Mafia Motorsports you'll find him.

well ive been slacking so quick update....i aquired another crew cab due to rust on the other cab that i didnt want to deal with.... might have been fine but i dont need it to rust out in a few years after its all done...i want to drive this unit full time....so i got a 2wd crew cab from a guy ive done some work for in town told me i can have the truck if i pull the engine....so the last 2 days myself and a few buddies tore out drivelines and front ends, and cabs i put the 80 cab on my 4x4 frame whish i kind of like the 73-80 front end they look more " heavy duty". Also ordered a crossmember from avalanch engineering, and searching for a 8 inch lift that om hoping to have for next weekend....

That guy has a few divorced NP205s on ebay almost all of the time. I had a divorced 205 from a Dodge many moons ago, and sold it for next to nothing. Didn't need it but have wished I would have kept it.
