Based on BSFC calc, the stock fuel system supports 537-572 hp depending on whether ur using 80 or 85% duty cycle on the injectors and assuming the injectors each flow 21#s/hr. So the heads/cams stock block modded motors are already close to the edge on the fuel system. Should be ok for stock motors. Then it becomes an issue of whether u r running E85 all the time or end up blending fuels which is where the fuel sensor comes in.
