You are way ahead of the cab only for $3k. Lots of good parts and options there.

I have rear door felts and door rubbers if your interested. New in box, just pay shipping.
Thanks I'll have to get it home and go through it I know I may need the carb engine harness and a dash but theres a lot of parts in Totes to go through
So I will have the truck home tomorrow and then I'll be able to nail down whether it's a carb'd l29 and whether the aluminum radiator I ordered will fit.
In the mean time I have some ideas floating around.
First being, I've already adapted the Allison and the 7.4 will bolt right up but is have to find a standalone tcm that actually works. (pic below)
Or do I discard the work/money I've put into adapting and stick with the th400/205 and get my driveshafts swapped over.
Of course I'd love to put a Cummins in this(always have) and that could be mated to the Allison via an adapter and possibly the same tcm but I'd have to put some serious money into the trans to hold up.
I don't know if this is worth it just to retain the magnum and current crossmembers and driveshafts.
Or start over with a built 47re and adapt that to my 205 after rebuilt with the magnum shaft removed.
I am a little stymied by the over complex computer controlled Allison but I like the way everything fits in the chassis including the full 3" ss exhaust I just custom built around the magnum etc

I'd need to reach out to them to confirm feasibility of course
You may be right! I'd have to confirm with ord I guess but I think the th400 is quite a bit shorter in length. I wonder if the th400 ratios would work well with a 5.9l Cummins
They don't.
Bummer but it may be a step in the right direction. If I can get the adapter to convert the magnum
Almost need OD to make the 6bt fun don't you?
I know they lunch overdrive even in the nv5600 but I have not much Cummins experience in the light duty market
You can get the Magnum in a variety of different input spline counts.
I say run what you have now without doing too much and concentrate on getting the Cummins and whatever transmission you prefer, I know the Allison was offered in busses behind the Cummins so it's good enough
old 06 f-650 rollback we had were i use to work was factory 5.9 cummins / allison trans , just need to find the right combo of parts .
Most of my cars that I've not driven at least a once or twice a week I usually put some kind of batter disconnect on them or pull the ground. Mostly because the battery would die, but seeing what you just had happen makes me think it's a good safety issue.
Thankfully the truck was far enough from your house...

Yea I'll definitely just get everything goin and run it until I decide. I'm pretty sure the Allison would need a health rebuild to handle a 5.9l. Then I am back to dealing with software which is opposing one of the main reasons I want a mech diesel. The NV4500/5600 is probably the smartest way to go imho.
Also I'm kinda worried about my d/s's and axles if I were to put my magnum behind a 5.9l. I imagine carnage

I’m definitely voting mechanical Diesel and manual trans. No drama, no wiring, no b.s.
You'd be a really sad fella with a 400 behind a 12 valve
them old uniform trucks and potato chip and bread trucks had 4cyl cummins bt engines and th400 and they were dogs . so i dont want to think about the 5.9 engine combo .
