40 Ford moving while engine out

[Zax40]

I pulled the tired flathead out of my 40 yesterday to eventually swap in a rebuilt one I purchased. I want to clean and repaint the engine compartment while it is out. Currently I have a bottle jack under the transmission to support it. With the torque tube setup and mounts on the transmission would it be safe to remove the bottle jack and roll my 40 out of the garage so I can power wash the engine compartment? Or would that put to much stress on the transmission?
