yep did it in my 68 dart sedan that had a 73 k-frame with 318/727
I had flowtech headers, unbolted pass side header/removed pitman/idler/center link/ends as a unit sliding them out of driver side header.
then removed starter/oil filter/dist/unbolted motor mounts/jacked front of engine up 2-3 inches, then droped the pan loose, unbolted oil pump/tube droped it in oil pan, then slide it right out from under the engine/trans bell...went in same way with pump/tube in pan.. get pan up in there, bolt pump up then pan bolts up.
I guess I could have rotated the crank walking the pan out leaving the oil pump bolted up.. but the extra work made it a lot less headach in the long run by having plenty of work room with headers but I was by my self at the time.
good luck and have fun under there.
