    I'm running a 110 gph on my 400 sbc, and ran the stock gm on my 350 with a slightly larger cam with edelbrock heads, so I would say a stock gm would work just fine. Just my .02$
    This wouldn't have happened if only you had been paying attention!

    You can get away with an 80GPH or 110GPH and have it set at about 5.5 PSI. The Holley 12-834 or 12-327-11 will be a great option and wont break the bank and no need for a regulator, but it IS suggested...you want to know whats going on and just because these pumps come preset, does not mean they are putting out that much PSI. It could be more or less.
