I also went from the bottom for my car. Not that hard, only issues I had were the brake lines getting in the way of the wheel wells.

 

I have taken it out the bottom twice now. I can do it myself in about 3 1/2 hours at a comfortable pace or in about 2 1/2 hrs. with a buddy wrenching with me. So easy, I am considering removing the engine the next time I do the spark plugs to save time ;-)

No need to remove bumper cover unless you are worried about dropping a wrench on it. I made a bar that allows me to hang a lift strap off either end around the 2 frame horns so I don't even have to remove the radiator anymore. The crane hooks in the middle of the bar. Works really well.

I should post pictures one of these days.
