You guys are right ... It occurred to me in the middle of the night that when most people do this job, they jack up the whole car first ... so the wheels are already pulling down the frame. So when they start jacking the engine, it goes right up. I did it with the car on all fours ... so all I had was the weight of the frame. All I had to do was jack the engine to the point where the wheels starting acting as a force of gravity, and up it went. Not really sure why that didn't occur to me before ... simple physics. And like in that pic fulcrum posted, the frame isn't much mass.
Something to keep in mind if you're doing this without jacking up the whole car!
