I don't like Holley fuel pumps. When ever you are looking at a part and the recomended item to go with it is the rebuild kit for the very same part, Just doesn't cut it. I passed on 2 of them once. They were free. Both needed rebuild kits.
I can't recomend any fuel pumps until we know how much boost you plan to run. You need a fuel pump that can supply enough fuel at about 7PSI above your highest planned boost setting. So if you are planning 15 PSI boost, you need a fuel pump capable of suppling enough fuel at 22 PSI.
If the fuel pump can't supply fuel above the boost pressure, fuel can't travel into the carb and you just leaned out the engine at the worst possible time.

get an msd pump thru jegs they will support approx 500 hp at 40 psi more at lower pressures, all of the areo motive regulators are boost referenced i think, the only difference between a referenced and a non referenced is that there is a nipple on the spring side (top) of the regulator that allows boost pressure to increase fuel pressure at a 1-1 ratio to allow proper operation of the bowls and jets

How do you check your air fuel ratio? Do you put a wide band in the exhaust and make sure it's not running lean under boost?
