72 K20 2nd Gen Cummins Swap

[Bryce80]

Here is my project, picked up the truck cheap back home. 72 Chevy K20, originally was going to put a 383 in it but somewhere between when i picked it up and now decided a 2nd gen cummins would be a lot cooler. Will post progress as i go.

Got the truck home and started tear down, the rust is pretty bad on the cab and the bed.

Took the axles to WFO in Auburn, CA (great company). Had them go through the Dana 44 front, added some knuckles and cross over from Off Road Designs. I know its light, at this time i was still thinking about going with a stroker. Swapped the back to a 14 bolt. Went with a skyjacker 4" lift with some additional hardware from ORD.

Got a quote for repair of the bodywork and needed to change my pants. Looked around and found a gentleman that refurbishes them out of Washington. He had the exact same cab (high hump, no ac, cab/marker lights) so I picked it up.

Now I am committed to going with the Cummins, lol. Got the motor out of a running truck(1995, 2500), drove it, pulled it and put slapped together a stand for it. Picked up the cross member from Autoworld Conversions and got it in. Located trans x member and started boxing in the frame, with a kit from Rob Bonney.

[Bryce80]

Got the advanced adapter kit for np205 to NV4500, had a shop do the work for the larger bearing. Put them together, put the motor and the cab on. Zero clearance. My next step will be modifying the cab to provide some clearance. I could do some modification to the mounts but I will go with modifying the cab.

Ya I bought the lift pucks. I cant' really remember were but there is some if you search 1" lift block. I made solid aluminum blocks for the bed. Not sure if the body lift helped but i didn't have to modify my cab. I also used a cross member from autoworld.

Off road design sells individual pucks

More work done, traction bars, front coil overs/long arm/link and cross over steering added. Mocked up with 37s. Also talked to the guy I am planning on having do body and paint and am planning to go with this sleepy hollow color, what do you think?

[Bryce80]

Intercooler pipe work and drive lines installed. Ended up going with a ICT flat plenum cover, now I have clearance to the hood.

[Bryce80]

Painted the rear suspension in place, pulled the front end, disassembled an painted it. Cold air intake on. After suspension have to use some baby tires to get the truck in and out of the shop, looks ridiculous but it works for now.

That's coming along nicely. Good work

[Bryce80]

Got the alternator and belt on. Found a compact master that fit. Checked for fitment with pedals. Picked up the bed and put it on the truck first time with all four wheels on. About to send off for body and paint. My opinion but I think she is looking good!

[Bryce80]

Off to body and paint. Won’t have any updates unless the guy lets me sneak some progress photos throughout. Maybe if the interior I ordered shows up I will post some photos of those pieces.

Cool as heck build man! Wish I could do a 12 valve in my 64. Maybe some day haha Used to have a 98 dodge with a 12 valve and 5 speed. Loved that truck. Made an honest 300 horse and got over 20 mpg's. Sold it with over 300K on the odometer and she was a leaker but a good runner haha

Awesome build and great work on it. Is that the ORD setup for the front suspension? I have used autoworld crossmembers on a couple swaps and I've found they really mounted them high and I've had to raise the body on them a little too.

I think the only things I'd change on your build is ditch the auto style brake pedal so you don't hit it when you clutch it, and I'd try to move the rear axle back to get the tire more centered in the wheel well. That's just a pet peeve of mine. It looks really nice though!

Thank you Dieselwrencher most of the suspension parts are from WFO. I have the smaller pedal pad for the brake whenever i get to reassemble. As it goes with these projects, never ending changes, I have decided to coil the back and will be able to center the rear while doing so. Sorry for the late response. Haven't really been paying attention since it has been at body and paint.

Been a while thought I would share a little progress. Gentleman that has been working on the body went down for a few months (soccer and collar bone ouch!). Received some photos from them today. Making some progress and first look at some of the color on the truck.
