never seen it done, should be nice after its done though

The T-19 behind the 6.9 has a 4.1 first gear. The pattern is the same as a T-18, the standard Ford "butterfly" pattern. Input shaft splines are the same. One area of uncertainty is the input shaft length. IDI (and maybe DI) diesels use a 1" spacer/adaptor between the block and bellhousing, so that may or may not mess with the input shaft length. I would check with AA on that.

There's no difference in input shaft legnth, along with that 1" thick adaptor, the flywheel sits back an equal legnth. The diesel T19 still has the same 6.5" input shaft stickout common to most other ford 4 speeds. The diesel trans may have the 5.11:1 first, which is followed with a pretty decent ratio spread for that engine. Maybe take a trip over to www.oilburners.net I think that there may be at least one member who has done that swap.

There are quite a few gas to diesel conversions being done now days. There is a site called cumminsconversions.com or something close to that. They have a lot of onfo on all kinds of diesel conversions.

He's putting a 6.9 in it. Not a cummins. How the hell would fordcummins help? Anyways, I'm sure it will work out fine. Just get goin on it and you'll figure it out then.

It will help him to know that he is not alone. A lot of folks install diesels in place of their gas engine.
