You need to cut the frame to get it in, forget it.

Yes you need to cut the frame.

If you really want to put the 400 engine back in then all you would have to do to the frame is machine some spacers up and get longer bolts for the head mounts. There are quite a few parts you would need to have off both the 600 and the 400 to do both conversions. Good luck anyhow.
