I think you are going to have to. I was fortunate enough to have access to a friends lift, but I required about 33" below the lowest part of the bumper (based on my engine and dolly). The way to tell is to measure the distance from the from the top of the engine to the bottom of the engine (you will have to eyeball some of this) and then add the height of your dolly.

Due to the limitation of your jack height, depending on what you have, you may have to lift the car in stages, or raise the car, lower the engine, and raise the car over it.

You may want to think hard about whether you are going to drop the engine alone or engine and tranny. I started out with the intention of just dropping the engine. Then, 2 things changed my mind:
1) I realized with the difficulting I was having aligning the 2 to separate them, the put back would be a lot more difficult.
2) I realized that with the engine drop, the weight of the engine will cause the tranny to pivot and help with the alignment, but once the engine is off, the transmission will rotate back into place. It will require some effort to tilt the transmission to re-mate the 2.
3) Finally, for whatever reason, when I pulled the engine back from the transmission, I did not have enough clearance in the engine compartment to remove the engine from the transmission mounting bolts. I need about another 1/2-1".

I know others have done it, so I imagine its possible but others had advised me against it and I am thankful I took their advice.
