Looks good, Larry! I like the "Heathen" title! [ddd
Your fuel issues: Vented cap? Vented tank? Self priming pump?

Your fuel issues: Vented cap? Vented tank? Self priming pump?

Thanks, Doc! The tank is vented, the cap is vented, the pump is an inline electric. Under much acceleration, it rarely gets to 60 mph without running out of fuel. We reset the floats, made sure everything was working yesterday. I even removed the Mr Gasket regulator and the fuel gauge block to make sure there aren't any restrictions. No dice. I'm thinking about using a 20-30 gph, 10-14 psi inline pump, but the one at O'Reilly sold last night, so I need to wait until Wednesday for them to get another one. (The joys of living in the middle of nowhere)
Some pumps won't pull fuel worth a damn, but they'll push it. If you have such a pump and it's mounted above the tank outlet, it'll starve when gravity can no longer keep the pump "wet" at the inlet.
I'd put the regulator back in and plumb a pressure gauge... 5-7 lbs for a Holley, if you still have a Holley on it...
.
There's lots of flow out of the tank (gravity from a port in the middle of the tank at the lower edge), and the pump flows well. It'll turn 4k rpm at a standstill, but under a load the engine just sounds and feels like it's running out of gas.
I run a little in-line Carter electric pump on my 300 Ford 6cyl dragster with a Holley 3310. It goes 118mph in the quarter mile. I therefore don't think you have a fuel pump problem. You should have enough fuel in the carb float bowl to get you up to 60. Does your pump have an in-line filter? You might want to disconnect the fuel line at the carb and check the flow into a can.
I changed pumps....the car runs great!
