Project EFI to Carb in my 2007 Silverado

[phantom405]

Im not sure, he just said dont use any type of holley electric fuel pumps, the one my dad told him about must have been pretty bad to run a 700hp 540, and he said go quick fuel, hes an engine builder for some of the fastest airboats in FL

Thanks for the info. Plenty of people run the pump I'm going to run including my buddy with a 505bbc on e85 that makes 550 to the tires. I'll try this and if it doesn't work, I'll look elsewhere. Thanks
