Maybe I was making it seem a bit TOO easy. When I said siphon al the fuel out, I really should have said:
Pull the fuel pump, check the sending unit for rust, verify the fuel pump works, reach in and clean out the tank with some old rags......
THEN add gas, flush, replace fuel filter, and give it a try.
A friend owns a shop nearby and offered his help since it is staying in the family. I'm having it flat-bedded to his place. We are going to flush the tank and lines, change the filter, and clean everything out. We'll also check the belts and hoses and for anything else that might have gone wonky after such a long nap. I suspect the tires aren't worth trusting after all this time which is a shame, because they are factory spec Goodyears have all sorts of meat left on them.
Here's some terrible pics, but you get the idea.

Reason: added pics
Nice car, the C4 with the LT4 is one of the more desirable years, that car will appreciate! The tires might be okay for short trips around town if it was store inside, UV from the sun is generally what wrecks havoc on them, but yeah generally they say to replace them every 6 years.
I would check with some of the more informed owners here, but you might want to keep the tires when you replace them. Some guys who go to top end car show(forgot the name) could use those OEM tires for judging purposes
You can certainly hold onto the original tires for someone who needs them for NCRS judging but only if you have room. I tried to give the ones off of my 92 away a couple of years ago with no interest. They also had great tread but showed signs of aging and were very hard. If you wind entering an NCRS event you will need to trailer the car there since it is not worth tearing up a quarter panel if an old tire lets go on the drive there.
Be sure to spray the tires with armor all and put them in black trash bags.
then don’t stack them on top of each other.
Make small hangars from coat hangars, using Plywood with slits cut into it so they conform to the tire rim area.
that way, no flat spots, no squeezing the carcass with no air in them causing inter rib cracking.

I question the use of Armor all, maybe there is new info but I remember that spraying it on your dash will cause it to crack over time, but I could be wrong.I don't know if all that prep for storage is worth it to the OP, someone had a tire FS with the same idea and it seems no one was interested, I'm not sure if they even sold it
That's a sweet LT4 car. A little mechanical rehab and check-out, and a good bath, and she'll be like new. Keeping that car is a no-brainer. Punt that Beemer if you need the garage space. You now have one of the nicest Corvettes ever built, IMHO. I owned an LT4 car for a number of years. They are superb.
Good advice from cadmaniac from my experience. My 91 sat for 12 years with a full tank. I pulled the pump/ level sensor assembly before I started it and it was a disaster, big mass of rust and the gas smelled like paint thinner. I drained (siphoned) the tank, wiped the tank out as best I could with a rag wetted with fresh gas, installed a complete new sending unit assembly with new pump and pulsator, replaced the fuel filter and flushed the fuel rail and the lines to the tank with fresh gas. I've driven it a bit over 1000 miles now and had no problems.

The car is finally coming home tomorrow! Covid moved back the schedule a bit. My mechanic friend changed/flushed every fluid in the car, including the gas. Every filter has been changed and new plugs and serpentine belt installed. After a trip to the tire shop for Continental EC's and an alignment it will be ready for a roadtrip back to my house. I can't wait!
