Man, are you going to have a long drive shaft. I would think close to 5ft I think it will be around 58".I would have got a longer tail if there were better communication with the builder.The 727 is 35" th400 is 28" ps:I ordered a PTC 9.5" converter will be here in 3 or 4 wks

how tall is it in the back from the mount point to the top? Interested in comparing it to a Nag1 and TF8 I have to see how much cross member surgery I might need. Thanks

The trans and engine are test fit so I can make a trans mount but the input shaft looks back too far for the converter pilot.

I notched the back of the factory trans x member 1" x4" wide and it fit the th400 nice so now to make room for the mount/bushing.

For what it's worth, I had a buddy with a '71 duster 20 years ago. When he got it...It had the top of the cross member cut out exactly like you've done to make yourT400 fit. Someone had chopped his out to put a 3 speed manual in the car, and the cross member was in the way of the shift rods if I remember right. This was a lowly mid 13 second car... nothing crazy.
Anyway... We converted it back to a 727 almost right after he bought it.
The odd thing was that it would break flex plates and trans mounts on a regular basis. After about 4 or 5 of them (even aftermarket SFI ones), we suspected maybe the missing frame cross member section had something to do with it.
My dad cut a piece of cross member out of a donor car and welded it back in for us. Never broke another flex plate again!!!!!
So just my 2 cents from my one and only experience.... with that crossmember piece missing it was a disaster. Thank you I could always weld some angle in the cross member inside.I had to start somewhere.
