Measure the height of your motor as best you can to get the height you need. Mine needed about 32 inches. Probably your jack won't get the car that high without putting it on blocks.
The advice to pull both the motor and the tranny is sound. It's a lot easier to mate the clutch and tranny on the ground than in the car, especially if you are alone. Remove all four bolts with the jack under the motor. Carefully pull the jack and motor rearward while lowering very slowly. (Do this after disconnecting everything, including of course the shift rod.)
You should make one of those u-shaped carts with wheels to accept the motor and tranny when you get it down. It will save a lot of aggrevation. The motor-tranny assembly weighs 500 lbs and is a bear to move around unless on wheels.
