255 lph should be good enough for over 600hp.
BSFC ~ .5 meand 600hp * .5 = 300 lbs of fuel per hour
to convert pounds of gasoline to liters, divide by ~1.6
300/1.6 = 187 lph
I went with the 255, even though my head/cam LS1 puts out less than 500. You never know when a built LS2 comes a-knocking on my garage door.
