I use an engine crane to pick mine up off my jack and onto the stand. I built a fixture similar to the tool shown in the workshop manual for my jack. It works with all 911 engines 65-89 that I have tried with it.
This jack fixture solidly supports the engine with or without the transmission and allows the space required to separate or install the trans.
It works well with or without exhaust, but on the 914-6's, I typically take the exhaust off.
