No not yet. Transmission is still in. Have kid stuff to do all week so probably won’t get it out till Friday or something
Found the problem…
Apparently the snout of the t.o. bearing was too long and melted to the clutch disc hub. Aluminum melted right into the splines. Amazing that that small amount of aluminum would drive a 7k truck right over parking chocks!

Well now that I’m thinking about it, the disc is engaged the shaft all the time. 
Did that seize it up so the clutch couldn't be released?
Man you're a pioneer in weird failures.
I spoke to a centerforce tech that asked me to send him a bunch of pics. See if they see somethingMan you're a pioneer in weird failures.
Not sure 100%. It sure looked like it was releasing but it definitely wasn’t.
Seems to be a recurring theme with this build.
So is it okay for me to say something like, "I've never seen this happen with any of my automatics"? 
@Fastereddie I may have missed it but was there any feedback from ORD concerning the 465/Magnum interference problem?
Gee thanks lol
No, I never contacted them. It was 100% my fault. It says in their instructions to make sure the the shaft isn’t too long.
I checked it and thought It was good. It wasn’t
Yeah you can say it… I dish it out, I can take itSo is it okay for me to say something like, "I've never seen this happen with any of my automatics"?
From the face of the clutch disc hub to bellhousing face looks like 3-5/8”.
From transmission face to end of melted t.o. Bearing is about the same.

So you basically squished the clutch disc to the flywheel with the throw out bearing inner piece.

It is. But having the disc stuck against the flywheel would still allow the power to transfer. Instead of the pressure plate clamping the disc to the flywheel the throw out bearing was.
I’m guessing the melted aluminum on the splines also added to the problem by keeping the bearing from retracting away from the pressure plate.
What part number release bearing did you use on it? I wonder if it was boxed wrong.
Correct. I just got back from Napa with a new slave/throw out. It measures 3-3/4”.
Definitely will smash into the disc hub.
The release bearing/t.o. was a luk replacement from summit. The one I just got from Napa is the same.
This is the number I got for mine when I put the last trans in. It is different than yours.
