I currently run this one: http://www.summitracing.com/parts/hly-12-440-11/overview/make/dodgeIt is the common Holley unit. I had some fuel delivery issues last year while breaking in the Lunati cam. Lately while running the car hard it has run out of fuel at WOT. The fuel pressure at idle is in the 7 range. At 3000 rpms in Park I can see the filter starting to empty out. The pressure slowly drops as well. I'm sure it is only worse when under a load while driving. The float level is dead center in the sight plug. I have a 3/8" fuel line from tank to carb. I recall reading that there is a better flowing Carter pump available. Any comments on the Carter unit or others?

Any pump that works at all should be able to supply fuel to the engine with no load. A good first step would be to run a hose from a can of gas to the inlet of the pump to see if that part works.
Master, again and still

The Edelbrock while expensive claims to be able to support 600HP--I have used with great success. You must pay attention to details and not choke it down with wrong fittings etc.

I used my original 1970 440 six pack pump on my 496 stroker 6 pack without any issues whatsoever.

The Holley I have has a 5/16" outlet. I had to use an adapter to a 3/8" for the line to the carb.
