What type of AIR FILTER are you trying to run through ? ... if any.
K&N 14x3, I could do a run up to 4000 without one to eliminate that as a variable.
A 14x3 on a 500 inch motor ? .... 
Yes .. try a shot WITHOUT an filter. Or at least double-stack them.

Well, thanks for the replys
I really need to do some troubleshooting here before I throw money at more parts.
I have a checklist...
Pull the outlet side of the pump hose off and use the started to see if its putting out the fuel it should.<<<<<<<>>>>>>>>
Volume check off starter only is not enough,the car should run for 20 seconds on what is in the fuel bowls.Check with car running  
Better idea, I can do that

If I double stack them I will have to pull off the hood, as it is I have maybe 1/4" clearence between the lid and the hood. I'll do a run without but if thats the issue I don't know how to get more air filter under there.

K&N makes a filter lid http://www.knfilters.com/universal/X-stream.htm I have a spare HR 220 what fuel doesn't leak out might help your possible fuel starvation issue

Fuel pressure ?
Fuel pressure at idle and under no load is fine, it stays steady as I open the trottle as well but this is under no load, the only fuel pressure gauge on the car is under the hood.

Rig up something so you can see a gage while you drive it. I rigged a simple mechanical gage up into my car for this before. It's fine for a testing prurpose, but take it out if you do any real driving. It sounds to me like it might be something else, but do those tests first and see what results. You should be moving enough fuel for what you have.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

I need to figure out how to do that. I was hoping to rig it outside the car but its not going to happen, maybe a temporay fuel pressure rig inside would be a good idea, maybe vac too?

Another easy test:
Make sure the float level is correct, find a stretch of deserted road, hold it wide open until it falls on it's face then turn the ignition off immediately, without letting up on the throttle. Coast to a stop and check the float level again. If the bowls are dry, you just eliminated a bunch of stuff on your checklist.
Jim
I can try that tomorrow, I will be on some back country roads. If the bowls are empthy after this test I just prove there is a fuel problem but it doesn't help me identify where the problem is right.

Moper, I'm thinking a couple 1/8 npt fittings and a length of hose and I can move the gauge from under the hood to under the dash. You said you think it may be something else, care to take a stab?

Right, it simply tells you that you're running out of fuel, but tells you nothing else.
It will, however, eliminate things that have been discussed such as improper jeting, air filter, wrong power valve, etc.
