It was coming from the fuel bowl vents I believe it would really shoot out when I would crank then when I stopped cranking it would blast out. I ended up clamping my fuel line also. I fixed all those issues I believe. I was able to barrow my friends timing light, vac gauge, and tac meter to get it dialed in tomorrow. Seems to be running wayyyyyy wayyyy better even now though I only tuned it by ear.
I almost forgot is that 12-14 timing with the vacuum assist detached and plugged from the rotor?

Yes, the ignition timing should be set without vacuum assist to the distributor. Pull the hose off the distributor and plug the hose. Probably the hose comes from ported vacuum
In a nutshell, the difference between ported vacuum and manifold vacuum is that manifold vacuum has vacuum at idle. Ported does not. But as you raise the RPMs, ported vacuum goes up. Adding ported vacuum to the distributor at higher RPMs makes the timing advance. Good for fuel economy.

Thought I would give an update and say thanks again to everyone for your help. Truck is running like a top now, 12 btdc timing with 20 psi of vacuum. Idles smooth, accelerates smooth. It's probably running better than it ever did before it got parked. Thanks again!
