Final Check List Advice

[Northwest Outlaw]

After a year and half i'm within a week of getting the '61 "Boomstick" back to running and driving status. Check out my build thread for the long version, but the short story is I've swapped in a SBC 350 and TH400, disc brake conversion on the front with power brakes booster, lowered 2.5"/3" (spindle and springs), new radiator, engine bay wiring, and new driveline.
This is my first project so i'm looking for a list of all the things i should check before trying to put her in gear and drive off into the sunset. Thanks in advance.
