fuel pump size, A body tank

let me see if i can say this so it makes sence, lol
i am building a chevelle, looking at the Spectra FI tank, upgrade to a diff pump, will be running LS3 intake/60 lb inj/stock fuel rail, aprx 10 lbs boost
what size intank pump will be enough, 255 walboro?
with all the factory cars running boost, i fig the stock pump limits are well known
this is my first attempt @ FI, the other LS/boosted engines were carb'ed

The Spectra pump is junk, mine only lasted 6 months. I think you'll be fine with a single Aeromotive 340 or one of the new 400 lph pumps.
