Holley 8007 (390cfm) Problems

After searching the forums, I still wanted to posted this up as I haven't quite found the answer.

A couple days ago I drove the barracuda to a friends house, no problems. Started up, ran smooth.

I had to fix the turn signal relay as the previous one had burned out. I replaced it with the exact same model.

The car sat the rest of the day and again started up fine. As soon as I turned the block to head home, the engine started sputtering. I'd press the throttle and the car would spastically accelerate. Eventually it just died.

Pulled over and took the air cleaner off. The fuel filter (clear plastic universal) was completely full. When manually accelerating from the carb, I had smoke coming out of the barrels (guessing this is fuel boiling?).

Eventually after a lot of stalling, I got the car back to my friends and parked it.

Went back to it today. Pulled the carb off. Sprayed it through with sea foam carb spray to remove some gunk. Tried to pick up a new fuel filter, but they seem to be in high demand in my area (had to order one). Flushed the current filter with the sea foam spray as well.

Put the carb back on, reconnected all the hoses and again the same problem. Fuel filter fills completely with gas. The engine keeps sputtering. Now it's running for a bit, sputters, then dies. I've had fuel overflow from the carb, adjusted the float needles. Also had fuel skyrocket out of the vents. I've tried adjusting the idle, the air/fuel mixture screws. Nothing.

I'm at a loss. I'm not sure if there is too much fuel trying to pump in or not enough. When I accelerate from the carb, it sounds like it's trying to suck in a lot of air.

I haven't done anything technical yet (checking vacuum pressure, etc.)

Should also note, car is a slant, 225. I've had the carb on for three months now. This is the first time I've had any trouble with it.

I ultimately may have to take it to a shop, but wanted to try and fix it myself, with the help of fellow gearheads of course.
