You guys kill me with your fuel pressure settings. No modern 4-bbl carburetor needs more than 5 psi to keep the bowl(s) full. You need VOLUME, by using large diameter lines (1/2" or larger), but you do not need high pressure. All that will do is to overpower the needle and seat and allow the pump to blow raw fuel into the intake manifold, creating a tuning nightmare for you. This is not EFI, where more pressure will support more horsepower.
