couple of things, make sure carbs are for BLOW thru, not just blower carbs..not the same !! put a switch on the dash to be able to turn off fuel pump as a override(trust me) also make sure you run a boost gauge and a fuel pressure(electric) in the dash...you will need to do a return to the tank...can use a diesel fuel tank sending unit that has the fitting already there...I have done all these...

Not thrilled about it, but if it is the only thing that will work, then what the hell...

The Stewart mechanical pump will handle up to 1875hp in a blow through arrangement. I've seen them used in EFI applications with pressure up to 75psi and 450gph.
