The car had not been started in three years so, I had it sent to a Chevrolet dealership that has a tech with an excellent reputation for 2nd generation ZR-1s. I did that so when I got the vehicle home, it would be able to move under it's own power.
They changed all the fluids, drained and cleaned the gas tank, installed new spark plugs and a new battery, primed the oil and started the car. It has 9,2XX miles and runs very well. Since it can take quite some time to get it in at Marc's, I won't be pushing it until then.
As for the tires...I'm probably going to Hell for stirring up those keyboard bandits on that Fakebook forum. I knew a new old stock tire thread would get em all wound up. Those tires could come in handy one day but, it goes without saying, not for much driving.
