I turn the key on, wait for the EFI system to prime, scan the digital dash to make sure everything looks good, flip the switch to prime the oil system, then hit the starter.

I connect the negative battery terminal, turn the key to "run", let the fuel pump fill the carburetor,
pump the throttle a few times and fire it up.

Sometimes I might get fancy and pump the throttle from under the hood, with the air cleaner off, or might hook up
a battery charger for a few minutes.

Did this with the flat tappet iron head 440 that served me well 1990 to 2001. Pulled to upgrade with nothing wrong with it.

Just a year or even season at that... check the fluid levels, stick a battery in it or charge and hook it up if it's already there and turn the key like normal.
