I've been working steady on swapping. 97 p-pump 12v into my old Ferd. Previous to this I have never touched a cummins. Only IH I.d.i.'s. I love the idi but I wanted to see what all the hype is about. So I started hoarding parts. Fast forward I now have a ppump 12v with a g56 and 231d and a rotary pump cummins with a 727 slush box with np205. I like to do things in bulk. So I'm not hunting for silly brackets and hardware when I'm in the middle of something. I will get up the pics. There are a lot. Since I've been working on it for a month but just decided to make my thread.

Engine details.
I purchased it from the guy who built it bc he was getting married and wanted/had to liquidate all his toys. (Poor guy)
It's a school bus 97 p-pump motor. IH cast block. Fire ringed block. Marine pistons but stock injectors. Kdp fixed. Motor was rebuilt. Not just with a can of krylon. As for the pump. 4k gov spring and shaved fuel plate. Hx35 I rebushed. Usually when I post what I know about this engine I get a lot of ??? Wth ??? Yeah I don't know wha he was going for but I don't want to mess with anything until I get the truck running.
Trans is a 07 g56 from a rollover with 27k on it. It has a south bend clutch.
Tcase is a 231D.
I'm running 3.55s in the rear and about 34-35" tires
I'm running 1480 joints in the back and 1350 up front. I had a lot of 1480 stuff laying around and Jesse at high angle driveline hooked me up solid with a flange yoke for my sterling so it was a no brainer
I went with the dieselconversion motor mounts. I'm not in love but they'll do the job. I made my own trans crossmember and used the stock dodge trans mount.

I'll get more details and pics as soon as I get a chance. Let me know what u guys think.
 
Think we need some pictures!! But sounds like a good build first.
 
ok im going to try to upload the pics. i have been working on the truck for about a month so there is a lot of pictures to add

Turbo time . Had to choose between an h1c wh1c and an hx35. I ended up cleaning up the hx35 shaft on the lathe and re bushing it. I dont know where the truck is at really so im just gonna run this setup to get a baseline

Got an ox locker off my buddy. It had seen some abuse . the cross shaft welded itself to a side gear and broke the spring pins. I cleaned up the cross shaft and spiders on the lathe. She's good now. Ready to drag the sled thru the gate.

Waiting on a firewall plate from Jason Moyer then i can put the dash back together. This truck was a 351 auto.

For the clutch hydraulics i used a 94 ford master bc from advanceauto they are always aluminum and i bought a dodge southbend prebled unit from nick dybiec. I used the slave and stainless line from the southbend unit with the ford master. It's all the same bore and stroke so the clutch bled right up and its got a great feel too it.

These nut washer combo things ALWAYS rot away so i made my own from some lug nuts and washers. Then i just faced them on the lathe.

Time to get shafted. Front shaft was made from some old rear shaft parts i had. I ended up running 1350 joints. I robbed a 1350 yoke off of a 70 for the front 60. They are interchangeable.

Called Jesse at high angle driveline for thos baby. It's the slipper for the t case and its a 1480. U may ask y 1480? Well i had all the parts and shafts laying around to make my own shafts with 1480 joints so i am into all the shafts for about $325 after new joints. I also got a blank 4.75 square flange yoke for the sterling bc i thought my driveshaft was a 4.75 square. Well it wasn't. But thats what lathes and mills are for!!! I got her drilled out right and made the pilot ring to match.
