[shelby racer]

Hey Gang,
I am the proud owner of csx4788 which will hopefully be finished soon. I am having some problems with the fuel system and got into a discussion with my race car mentor. I am currently running the two -6 hoses from the two fuel pumps into a fuel block into the 3/8 " pipe connector to a holley fuel pressure regulator to a larhe summit racing fuel filter out a -8 aeroquip line to a -8 aeroquip fuel log to a holley 4150 750 cfm double pumper and measuring fuel pressure off the other end of the fuel log. The motor is a 1965 HM 427 (~10:1) side oiler with edlebrock heads (modified for a 2.19" intake) that should be putting out ~ 525 hp at the fly wheel. My mentor is telling me that I will not have enough fuel flow to the carb and that it would be better to move the regulator to the carb, run -8 line from the fuel block to the filter and -8 line from the filter to the 3/8 connector on the regulator and then (2) -6 lines from the regulator to the carb. Will I really get that much more flow by replumbing it as suggested? Is my flow truly going to be inadequate as it is plumbed right now? Thanks.
