1982 crew cab cummins "pieces"
« on: December 09, 2020, 08:21:50 PM »
so i picked up my crew cab a couple years ago as a 6.2 auto truck converted to a worn out 454, standard fleetside bed, no frills and a blank canvas. i wanted to do a diesel swap when i bought the truck, i was really wanting a detroit 4-53t, but thanks to the epa they arnt exactly plentiful anymore. i bought a bus to take the 12 valve cummins out of, bought an eaton fuller rtx14710c 10 speed, a 4wd front axle out of a superduty ford, and started the project.

i had removed the fleetside bed and the driveline, i had a steel flatbed i wanted to swap over so i can use it for a welding truck. took the cab off and started with a bare frame. i started with my custom 3 link suspension, and once that was done the motor swap came next. dropped in a freshly gone through 12 valve, used the industrial mounts, and made a crossmember for the trans. the eaton bolted to the cummins using a sae 2 flywheel housing, 17 inch flywheel and 14 inch pull clutch. the engine had an on board air compressor as well.

power steering was done by using a homemade adapter to run the stock gm power steering pump mounted behind the engine driven air compressor.

as for transfer case i was going to use a dana 24 divorced case but wound up using a married np241c, i had a custom adapter made to marry the case.

exhaust was handled by a 3 inch down pipe, 4 inch main pipe to dual 5 inch stacks.

im in the process of wiring the chassis and cab up currently, after the wiring is done i will be moving to the interior.

i want to update the interior to a nice set of modern seats, preferably heated and cooled leather just because i like the durability and the look.

i want to try to run 37 inch tires but i dont know if they will exactly clear my front fenders or not. defiantly going to run 35 inch tires but ill try 37s. i still have a laundry list of things to do to the truck yet, ill have some pictures tomorrow hopefully if i get some time at work,

this truck is prolly my favorite project ive undertaken yet, and i grin like a kid in a candy store every time i get behind the wheel of this beast.

once im on the road officially i am planning on doing some minor motor work, just 18* of timing, compound twins, bigger delivery valves, afc live, 75 horse injectors, and a few small goodies. theres a guy on the cummins forum who did a 13 speed conversion running the same engine setup im looking at, and he is producing 450 hp and just over 1000 lb feet.

now that im on winter break from college ive got my evenings and weekends back so im hoping to start making some serious progress within the next few weeks.

This is how she is sitting now. I havent gotten any more pictures of the progress lately. Mostly because on the outside it doesn't look like ive made much. The problem is I'm,in the wiring stage. I'm designing my own harnesses and all, ive got most of them installed just finishing up the cab wiring and headliner. I'm pretty good at wiring I'm just piticiluar. It took me 4 hours to build the chassis harness, 7 hours to install, and another 5 in the cab so far. But everything is wired up using the factory color coded wires, soldered connections, heat shrinked and taped, then wire loomed. But oh boy does it look pretty.

Then theres my fuller adapter to np241c its a custom milled steel plate, the 4x4 adapter off a 4l80e, the stock fuller yoke turned down, and a 32 spline output shaft welded to a custom adapter. If anyones interested in knowing more let me know.

And then my shelf, the truck came with one of those shelf it things installed, I decided to leave it and mount my cb, as well as weld a stainless plate to it to mount my boost gauge, perimeter, and air pressure gauge for the on board ait system. Interior is goimg black so i re covered the shelf, and I'm working on the headliner.

Your description answered my question about the front coil springs. Curious why you went that route instead of leaf?

Look great by the way!!!!

I run the coil springs simply because they ride better in my opinion. That and to be different. Im not fond of putting ford parts on a chevrolet, but the superduty coil springs ride 10 times better then the leafs. I started from scratch so it was just as easy.

Fascinating Captain! I have a '78 K10 that rides like a...truck. Would love to remove a leaf from the back and see what I could do for the front.

The pics don't reveal the other components needed, like control arms etc. Would love to see how you tied it all together.

I too picked up a 89 C30 crew cab, 454, with camper, wish it was a K.

I just made a 3 link setup. Ive got pictures of the links, ill see what I can find picture wise of the setup. Its nothing too complex, I welded some 3/8 plate down the side of my frame to mount my lower links to the truck, and have a section of c channel right before the frame swoops up to go to the k member. All the crewmembers were made from 3 inch c channel, and brackets were made from 3/8 plate.if you look closely at the bottom edge of the trans pic you can see the plate. The steering was a custom draglink made from threaded rod ends and .25 wall tubing, drag link was the ford part cut down.

As requested, some front end pics. The ride is a little squishy for me, but my engine and trans weigh 2000 pounds alone. Im going to see what the 37s look like and if its close ill order some 1.5 inch leveling springs which will be 7500 pound instead of the 5600 pound springs there now
