400ci to a 400THM?

Hey I'm looking at getting rid of my Jeep because I've run out of room, so I would like to take the built 400 and put it in my 90. My question is will the motor and tranny mesh? The tranny is a 400THM out of a 90, motor is a mid-ish 70's

Thanks for the help! That's good to hear, the motor is pushing 425HP and I've never driven it so I really didn't want to part with it.
