You should've been paying attention in math class back in high school!

BSFC for E85 is around 0.65 so that means you need 450 lbs/hour of fuel. E85 weighs 6.5 lbs per gallon so you'll need 70 gallons/hour at wide open throttle. 70 gallons/hour is roughly 270 liters per hour so the Holley pump should be fine. Double check with Holley that their pump is happy with E85. You'll need to verify that everything in your fuel system including the foam in the fuel cell is okay with E85. Otherwise you might be pumping goop into your engine.
