[thelittle289]

I know this is not the IDI area, but theres a lot more people reading the powwerstoke than IDI. now the question,Will a 6.9 bolt to the trans of an IDI 7.3. I'm looking at a truck with a blown IDI 7.3. I have a IDI 6.9 Is the bellhouseing the same bolt pattern, can I put the fly wheel off the 7.3 on the 6.9. Thanks fo any help!

The bell housing are the same but I had to add or remove a spacer I cant remember which to make the flywheel work. I put the solid flywheel out of a 1985 6.9 into a 1994IDI

I also had to lenghthin the clutch rod (the rod between the clutch fork and the slave cylinder) made one out of a shaft real eazy to do.

If I got a 6.9 flywheel would i still need the spacer. Right now my 6.9 is hooked to an auto and just trying to do as cheap nas possible. Where do you get the bell spacer. And in your opinoin is there a big diffreance between the 420 cid 6.9 & the 444cid 7.3. Both no turbo, so I didn't think there would be a noticable differance with 44cid of differance. I have a 99 7.3 but with a turbo you realy can't compair the 2, but my 6.9 has never let me down. Was planing on turning the 84 250 into a 4x4, have all the parts, but i figured it would be easyer to to put the 6.9 in the 92 4x4?

no the spacer goes between the flywheel and the crankshaft but thats if you are trying to put a 6.9 clutch behind a 7.3. I couldent tell a difference between the 6.9 and the 7.3 but I have never drove one with a fresh engine. If you are just swapping engines I believe you should be fine.

thanks JTA thats what i plan on just putting my old 6.9 where the 7.3 was
