here is a good link. Now this is cummins application, but lots of resources for the big transmission conversion...
I would really be interested in seeing some proven numbers on DT360s. The post above suggests 400 hp and 600 ftlb torque, thats a start. I can't find very much info at all on the 360, except lots of people complaining how gutless it is. I search youtube and can't find a single DT360 in a pulling truck or tractor, which makes me wonder if its really this 1000-3000 hp monster I've heard claimed. Am I looking in the wrong places?
It has a5.9 cummins manifold and a HX35 turbo. (1/4)
Is the Cummins manifold a bolt on?
I know the DT manifold can both be turned upside down.
Dang .I was in Albany sunday.
I would use the zf, make an adapter to make it fit, use the zf flywheel if the balance is correct. There are clutches to hold more power so not an issue. If you had a dt flywheel that was too big I would find a bigger lathe and make the FW smaller. I have done this before not a big deal. Or open the ZF FW to bolt onto the DT.
I think a RTO would require Huge floor mods to fit in there.
Call Columbus Diesel Supply, Scheid Diesel, Gene's Machince Shop, Hypermax, WipeOut Enterprises, or any other place that builds diesel pulling parts. There litterally is a metric ton of stuff for the DT 300 and 400 series diesels. IF THE TRACTOR IS RED, IT HAS A DT UNDER THE HOOD!!!I would really be interested in seeing some proven numbers on DT360s. The post above suggests 400 hp and 600 ftlb torque, thats a start.

.... the real question is would the DT flywheel fit inside the integrated bellhousing of the ZF5, so I could use the stock DT starter.
As far as medium duty stuff goes, here's what I have figured out so far.
They are standardized into SAE sizes, with SAE #1 being the biggest.
My DT has an adapter bolted to the back of it that adapts it to a SAE #2 bellhousing (it was an Allison auto in the bus)
Industrial IH IDI's came in bigger trucks with SAE trannys bolted to them.
The back of an IDI does not have an SAE bolt pattern in it; there is an adapter from the engine block to the SAE bellhousing, just like on the smaller pickup engines, but different bolt pattern.
Why don't you see a 360 very often in pullers? Because they all run 466s. Some of those guys are highly competitive.
Another question; what is the diameter of an IDI flywheel? Somebody here has got to have one they can measure. I don't think the flywheel that came with the DT is much bigger; but it's been a while since I set eyes on mine.
