It took me and a friend a good 15 minutes to get my engine in recently.
Assuming the clutch is installed properly, the angles and alignment are
critical in getting these units together.

Have someone underneath work a small jack under the tranny while you
work the engine on its jack.  The person underneath can see the angles
much better.  Off by 2 degrees up, down or sideways and it won't fit.
