Dumb Bellhousing Question
I just want to confirm that the 6.9L has the same bellhousing pattern as the 460 "385" engine, mainly want to verify that a 460 can be bolted to a C6 or T-18/19 formerly behind a 6.9L. Thanks!

IHC spec 6.9/7.3 IDIs mounted an SAE #2 flywheel housing directly to the engine block.

I belive it is BUTTTTT le me double check.... I know the 6.9 in a bus and a 6.9 in a regular truck has a diffent pattern... differnt adapter plates ... le me look this week end I have a 6.9 in my garage and a 460 in there also I'll unbolt the 6.9 bellhousing and see if it will bolt on the the 460... now if your truck had a stick just unbolt the bellhousing from the tranny and put the one from the 460 on there.. remember a 400m is the same bolt pattern as a 460 (doing a 400m to 460 swap on my truck (avatar) ... my buddy bought a diesel truck (deisel had a rod through the block) he put a 351 w in there but with the diesel tranny it seemed to be to high geared ... taking off in first was like trying to start in second... some people say the diesel tranny's are geared differnt thus I don't know and can't prove..

Because the bellhousing is seperate on the T18/19 transmissions(gas or diesel) and the transmission mount pattern is not different between the two in Ford applications, a T18/19 transmission can be swapped between diesel and gasoline powered apps, using the appropriate bellhousing for the engine.
A C6 that was behind a 6.9/7.3 IDI will not bolt behind any gasoline engine without using adapters.

The bellhousing that mounts onto a Ford spec 6.9 IDI will not bolt directly onto any engine(I don't know about 7.3 PS). The pattern on the block of the 6.9/7.3 IDI is the same as IHC MV pattern. The adapter used between the engine block and bellhousing on a Ford spec 6.9/7.3 IDI will only bolt to the IHC MV engines and the 6.9/7.3 IDI. It will not bolt to any non-IHC gasoline engines.

Just a thought about this topic.
Is it really the bell housing bolt patterns for the diesel and gasser C6s that are different, or is it just the ADAPTER plates that are different?
In other words, can't you just swap the adapter plate from the gasser C6 onto the diesel C6 and then be able to bolt the whole thing onto the 460?
Somehow it just doesn't make sense to me that they would have two completely different castings for the C6 tranny housings - which is what it would take since the bell housing and the tranny case are all cast as one unit. It just seems to me like it would have made more sense to use the same casting for the case (including the bell housing) and use different adapter plates to mate it to different engines......
