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.

my pump I went with the Walbro 255lph with a stock TPI 305. It was regulated pressure, and knew eventually I would want more power. I am glad I did, because when I swapped in my LS1 a year later, which wasnt planned, I didnt need to worry about upgrading my fuel system.
