Sorry to thread-jack but do you support the engine with anything else, or have you found that the m103 mounts to a stand fine without need for additional support? I’m looking for a stand to put an m103 on and found a thread suggesting the need for extra support. Seems like some use a bottle jack. Thanks.

I have an M103 on a 1000lb engine stand at the moment. No problems with needing any extra support.
