Using a 6.0 converter in a 7.3

[dieselcruiserhead]

Hi All,

There's a chance I might be replacing my engine on my 99.5 Power Stroke. My truck is a pretty stock and will never be more than 20-30 more hp I figure as I'm interested in mileage and longevity and I don't need a ton of power.

My transmission with 225K miles is actually original and is holding up. The PO I think did a good job of keeping temps down and its still doing OK (and I can't afford a rebuild right now). While I was there I thought I would replace the torque conveter though. Because (again $$) and because I figure I'll be there at some point I'll do a good torque converter then.

I've been reading and I guess BTS (or perhaps John Woods) recommends a 6.0 torque converter for 7.3 applications. I've heard conflicting info about whether the 6.0 torque converter bolts right up or if it needs to be built custom. You can get 6.0 converters for even $300. There is also a pretty good custom torque converter place here in SLC, they'll build me a 3 disk for $600 or a stock-ish but beefy/billet for about $300.

Let me know your thoughts...

I think the one BTS recommends is a 6.0 modified to fit a 7.3. Not 100% sure though.

BTS doesn't use any Ford converter, I promise you that!! He uses the 6.0 trans cooler and that's it.
John Woods was using the 6.0 converter in the 4r100 but it took a bit of modifying, but now John has found a better converter at about the same price and doesn't require the modifications. I would call John and see if he will sell you one of the converters he is using. I know to use the 6.0 converter you have to drill two more holes in the flywheel and tap them, and John says there are other internal mods that are required, don't count on him to give away any secrets. If he isn't using them any longer this should tell you something.

I thought the 6.0 was a bolt in and the 6.4 required the modification?
