The option to rotate the engine is a handy one.
If you don't have the means to build your own stand, the harbor freight 2 ton stand holds no problem. Had my fully dressed duramax motor on it and there was zero flex. I welded a few bolts to the head to secure the load at angles. I may fab up a ratcheting chain crank to assist in rotating though.
By the way, the fab is looking good, looks solid as crap!
