Engine install from below?

Mock it up and see what you need. Typically you'll need some sort of fixture to hold the engine and trans or the K frame and trans. Decide how high the fixture needs to be to work with your lift. A four post lift may not work so well depending on if you have rails for the tires or arms. If you have rails then you'll have to figure out how to fit stuff in from below.

I put the engine into my Duster from below but I don't have a lift. I have an overhead crane so I used it to lift the car body and then pull the engine and trans up and into position. I then lifted the K frame into position from below using a fixture on my transmission jack.
