Beautiful work! I wish I had toys like that, and the space to work on them.
But it makes me wonder... how do you deal with 22-year-old gas?

Seriously, there wasn't much left. I think a lot of what was in it evaporated, bu there was a gallon or two left in the tank. It didn't start very readily, and then after starting it didn't run too well. I warmed it up, and then Mrs, Racer 2.0 and I drove up the private road we live on to the paved road, turned around and drove back. I started it and moved it a couple times more after that, and it ran dry.
So I loaded the 5 gallon jugs I use for fuel when I go racing, and headed to the Arlington airport, and got 20 gallons of 100 octane low lead avgas. I dumped 5 gallons in, and it started more readily, and runs a lot better. It still need more work though, the rear carb has rust on the mixture adjustment screw and I can't balance the carbs if I can't adjust the mixture.
The reason I parked it was the oil consumption. As such if I put a fresh set of spark plugs in it, it will run quite well, and I can tune and adjust it as it should be. But after a short drive it would start fouling plugs and begin missing.
So I need to pull the engine and go through it, but right now isn't a good tome to do it. I have some options, a later VG30 V-6 and 5 speed, an L28 with the N47 EFI head, SU carburetors, mated to a Datsun Competition 5 speed, and an L28 bottom end that I was building for this car when I first bought it, that I could put my race engine head and carbs on and have a pretty good setup for the interim.
The VG30 might require modifications to the car that I would rather not make to a numbers matching original car, so I likely won't use it, saving it for one of the 280Z's I plan to build.
The L28 with the SU carbs and Datsun Competition gearbox were given to me by an acquaintance in the late 1980's, so it is an unknown. He said it was some kind of hotrod setup, but the only way to tell is open it up and have a look. I'm going to try and get it started sitting on the makeshift cart it is on, and see how it runs. If it runs well, I'll clean it up, lube/oil/filter/hoses and drop it in, as it would make no irreversible changes to the car, and I could drive it some while budgeting time for the rebuild of the original engine.
I rolled that setup out of the back of the shop the other day to size it up.
The third option is the ready to go bottom end and the currently idle race head and carbs. I took the head off the last race engine that was in the race car after a fuel pump quit during a race and the engine ran lean, causing detonation and resulting in a broken crankshaft. Again, a reversible option that will result in immediate fun drives.
Decisions.
