Can you swap a 6.9 v10 for a 7.3 idi without changing the bell housing?

The v10 Is 6.8 ltr engine probably will not bolt to a 6.9 idi
Edit I'm sorry I thaught I read 6.9 idi not 7.3 idi

What trans? Are we talking a 6.8 gasser for a 7.3? Or a 6.9 Diesel for 7.3? Don’t the v10s still use the big block bolt pattern?

The v10 uses the modular bell housing the 4.8 5.4 and 6.8 all use. the idi will not bolt up
Ah well that answers that. Still would be curious as to what engine the op is dealing with

I'm guessing 6.9 was a typo for 6.8 v10. sounds to me like the op wants to swap a triton v10 out for a 7.3 idi

I have a 94 7.3t idi also. But I thought the power stroke would be closer.

Lol that's a different story the power stroke is a many but the v10 has a bbf bolt pattern if I am not mistaking and the powerstroke is a little different

The IDI and PSD had the same bolt pattern. The IDI would be the easier swap for sure. Less wiring to redo.

One of the really cool things about the IDIT(or OBS IDI) is that the harness is basically self-contained - Literally just apply battery power to the main glow plug terminal, and switched power to the glow plug relay's small "ignition" terminal... and the engine will run! The glow plug relay, the high idle, advance etc... are all connected and work perfectly as soon as you power that primary lead.
(which also means that you just need to find a single wire out of the motor harness connector to get it to run).
Powerstroke on the other hand... Break out the schematics and start pulling wiring harnesses.
They do and they don't. The IDI's block pattern is hemisperical (SAE or native IH) and uses an adapter. The 7.3 PSD uses a spacer. On the transmission side, yes, the patterns are the same. I would make the Excursion manual. May want to investigate gearing. 4.30 ratio, as some of them had, may be less than desirable.
Big if. V-10 is part of the modular family... this post says its pattern is shared with modular V8s, 6.0L and 6.4L diesels
