I've found that a simple way to lift an engine for pulling the oil pan is to place a padded 4X4 wood post across the fenders, and use a heavy duty ratchet strap as a lifting device. Use the intake manifold or the rocker arm shaft as a lift point. That allows the vehicle to be moved if necessary while the engine is suspended. Ditto for removing/installing a SM 420 transmission- - - - -open both doors and put an 8 foot 4X4 through the window openings.
