The previous are all good suggestions. I think you might need an A-frame affair w/ a come-a-long for your sedan cruiser, if you you can't pick it from above externally. I have used doubled up 2X6's w/ a clevis thru bolted at the top for this. You can get he engine out by "walking" it out the door, just picking it up a little and leaning and setting it down. In this case you will be just lifting the back of the engine a little so it won't be too bad.
Boats are to be made of wood, otherwise, God would have grown fiberglass trees.
