Symptoms- still will barely run regardless of how much gas you give it and will eventually die... spits gas out of top of carb(slight backfire).

Is it possible it jumped timing a little...? Will that cause the above symptoms? It's the original motor... 216,000 miles(but doesn't burn oil yet!!!)
Try advancing the timing a little...it sounds like a carb problem or possibly a weak ignition problem/ not burning the fuel efficiently...check your spark plugs see what they look like and let us know..

Would a weak ignition module or coil cause it to not burn fuel efficiency?

Wooo Hoooo!! FINALLY got the problem resolved! Thank you to those that gave advice. But here's what fixed it for those still interested. Maybe it will help someone else.

I put in a new Comp Cams double roller timing chain set thinking that would fix it. Turned out there was LOTS of slack in the chain so it really needed replaced. Installed it straight up. Put everything back together, tried to start it and still had the exact same problem.

At least now there's no oil leaks in front of engine and I won't need to replace timing chain anytime soon!

SO.... I decide to get a rebuilt distributor because the old one had LOTS of slack in the shaft and figured I would replace it while I was working on stuff and it was about the only thing left of the ignition system I hadn't replaced yet. I lined up timing mark on harmonic balancer and I stab it... turn the ignition key and it fires up on the first cylinder and ran great! Evidently the problem was the distributor the whole time. But at least now I have new carb, coil, ignition module, timing chain, distributor and fan clutch(while I had things apart). I had just put a new water pump on a while back so I re used it.

Now it runs great with lots of power!
