Engine install from below?

Back when son was doing Fiero engine swaps we did the bottom in & out every time. Seems kind of intimidating at first, but boy is it easy when you get the hang of it. Built the whole thing on wood cart with Harbor freight casters & rolled it in and out. Nothing easier than assembling everything out in the open & dropping the car down on it. Didn’t have a lift. Used a harbor freight engine hoist, 4x4s & jack stands. Always want to have two independent supports.
