Dartfreak, I kind of skimmed over this thread. You'll just have to think over any obstacle that comes your way. Man, I can tell you I've pulled motors in the dirt, in the gravel, and every other undesirable surface. I've used Come-along from a beam, I've used rented cherry pickers on dirt using 2x12's under the wheels of the cherry picker and constantly moving boards, all with the cheapo headers. Yes, I've worked by myself at times when extra hands weren't available. If you can port your own heads, you'll install a small block in a A-body.
P.S. - I never take a hood off a mopar to pull or install a motor
