I also tore the engine down to replace the plastic oil nozzles with the billet aluminum ones, then found that I need a camshaft The rest of the engine looks really good but I'm going to put new bearings in since the old ones are out.

Clutch hydraulics installed, I used a Ford master cylinder and a 2000 dodge slave/master- removed dodge master and replaced with Ford master. Was fairly straight forward, press roll pin out, switch units out. Be sure to bench bleed the master first.

I installed the starter with the spacer for the 13" flywheel, I had to flatten out the spacer it was 20 thou off on one side. I had to grind out the inside a bit so it would fit over the starter too. Annoying...

Started working on the a/c compressor. I bought a new unit for a 94 because my clutch hub bearing was bad, and converting to R134; then used the rear cap/manifold off a John Deere tractor. Bought a lot of fittings/hose at nostalgic air parts, used them for TLC's in the past:

I'll update as it progresses, probably 3/4 finished now 3 weeks after taking the engine out of the dodge...

Yes, I got it here: http://www.nostalgicairparts.com/air...ad-back-22.php

They also have all the fittings you need. I had to re-locate the heater return bung as well, I made a return pipe and put it in the lower rad hose then plugged off the one that got in the way of the a/c fittings on the block.

I don't think you'd have to notch the crossmember with this depending on your mounting location, I still did but mine is mounted awfully low...

Looks great buddy , I just finished a 84 suburban cummins conversion , I see you retained the original fuel tank ... was that a diesel tank I know there can be a problem with gasoline tanks having zinc coatings reacting with the diesel .
look forward to seeing more ... great build !

Thanks, it's not the original tank, it's from a cab and chassis (I believe) and is 38 gallons instead of 19. It's made by Spectra and is specifically rated for diesel or gasoline- I read about the zinc/diesel meltdown and realized I had to replace it with something, got lucky finding the bigger one for not a whole lot more money...

Well it's been a while since an update. I've been driving it, getting better with each drive and haven't had too many issues. The divorced t-case has proven to be quite difficult to setup, the driveline angles need to be perfect or **** close... I also fought with a bent input shaft in the NP205, worn out output shaft causing play and an improperly machined 1410 sterling 10.25 yoke.

Lower radiator hose proved to be the tightest and worst. Don't know if I would have used the 1st gen rad again if I had the choice...

I then took the entire wiring harness apart and deleted all the gasser stuff. Then integrated the cummins into the factory harness, the old fuel pump relay is now the starter relay, ECU relay is now the gear vendors relay etc...

Seats and center console stolen from dodge, most every good part that was on the dodge went into this truck. I feel better about doing what I did knowing a lot of the parts are going onto the new truck.

Bed on for now, I'll pull off for finishing touches but I love the new length. Surprised they didn't make these trucks this length.

It runs amazingly well, I have had 2 mileage estimates both combined hwy/city and had a 20.3 and a 22.7 Really happy with it so far, but still a fair amount of details to finish up.
