trouble mating 5.0 and aod

We got a donor 5.0 from my buddies 86 m/t to go into my girls 86 aod. I swapped the flywheel and removed the bearing thats pressed into the crankshaft. WE dopped the motor in, and got the top 2 motor to trans bolts started fine. Tourqe converter and flywheel are lined up fine.

The problem im having is that I cant get the lower part of the motor and trans to come together. it has maybe a 3/4" gap that wont come together. Ive even tried using a C clamp to pull the block and trans together when I start the bolts. No luck.

The clamp pulls them together until they are about 1/4" apart, then wont go anymore. Ive tried lifting the tranny, but it ends up lifting the whole car.

Any ideas on what could cause the hang up?

Thanks in advance.

Yea thats what im thinking too. It was all the way in when I was dropping in the motor, so it must have popped back out.

When it wouldnt go in with a little pressure with the c clamp, I let off. Knew something wasn't right.

Yea i got the three clicks when I put the converter in... but it may have moved when I put the motor in... The tranny was a little low during the install.

Yes the motor plate is in.

Im going to try to get under there this weekend and see if I can jiggle the converter in without pulling the motor back out.

If I end up having to take it apart, Ill probably drop the tranny instad of the motor. It needs a good cleaning anyway.
