Not a big cost difference and both can be ran without a return line.
I will stew on this and decide later. The noise level on the first one is the hold back.

John,
The Aeromotive Street/Strip 11203SS Fuel Pump is rated at 150 gph (568 lph) at zero head and carries a $229 price tag at Summit.
The Aeromotive Phantom Direct-Fit Fuel Pump #18313 is rated at 180 gph (680 lph) at zero head and carries a $643 price tag at Summit.
At 150 lph, The 11203SS pump is inadequate for the fuel system you need to build. Its max flow capacity is right at your max demand threshold with no head room whatsoever. Additionally these pump flow ratings are measured at zero head. As soon as the pump begins to pump against head, its performance noses over.
Of those two pumps the pump that would meet your engine's fuel demands is the Phantom Direct.
One of the benefits to the Fore approach is they are OEM EFI pumps that are designed to run full on all the time for the life of a Detroit daily driver. None of the aftermarket pumps are designed to do that, which means the OEM pumps will not only have a longer life but likely perform better.
The Fore hat with two of the TI pumps is a marginally more expensive proposition at $675 but it is a forever fuel system. Using EFI fuel pumps with a carb means also using a Fuel Pressure Regulator to bring the fuel pressure down to the 6-7 psi that carbs require. That regulator adds about $200 to the system cost to get a regulator that will bring the fuel pressure down to 6-7 psi.
The EFI pump path is definitely a more expensive path. The more cost effective, direct path is Aeromotive's Phantom Direct package.
