I had to do the one on my 390 in a hotel parking lot a few years ago. Power steering but no a/c and a stick shift so no cooler lines. Tear down with hand tools, finding drain pans, hitching a ride to the parts store and all buttoned back up it took about 4 hours. Nice thing is the FE crankshaft pulley generally doesn't require a puller. That's another whole level of frustration when away from the shop and compressor.
