The 1000th E-85 post

ok , so i buy the quick fuel conversion kit from summit for my 750 holley double pumpers for $130 each

change the floats to brass ones

what about the air bleeds in the main body?

do they have to be drilled or can they be used as is?

anything else i need to know

ful system is aluminum cell,2 holley blues,fram filters,1/2 in aluminum line

Tommy you need to change air bleeds the fuel curve will not be right for E85

i would call QF to find out what size for your combination

Like Rick said... but I dont have any experience
doing a 750, I use a 1050 dom... call QF

Since you bought their parts you have a right to ask them a couple of questions, give QF a call.
E85 does require more fuel but not more air to go with it. I'd just follow the instructions and try it, watch the engine temp and shut it down if it starts to get hot. I'd be more worried about the feed passages in the boosters since a metering-block kit won't fix that area. You'll need to do a WOT, high-gear test to find out if there's a problem there. If so you should be able to drill the boosters out a little.
