HELP!! 360 Engine with transmission and headers?

Swapped out my son's headers last year in 70 swinger. Installed tti long tubes, had front end up 2 1/2 feet( car blocked and supported accordingly ) . Had the steering box out as we were swapping it as well, power steering pump, battery, steering linkage removed. Drivers side slide up from bottom and passenger side went down easy enough. Not a fun job but wasn't terrible.
