Fuel Delivery?

Alright, moving along on getting the ol stang ready for the 557. Oil pan - Check. Converter sent to Lenny - Check. Header fab set up - Check. Now to the fuel system. According to the math 840hp x .50bsfc = 440 pounds per hour divided by 6 lbs per gallon = 73 gallons per hour of fuel required to feed this thing. I know a BG280 is only "rated" to 650hp and the 280gph is at free flow but surely this thing flows more than 75 gph after the regulator? It just seems to me a BG400, ProStar 500, etc would be over kill. What do you guys think? With the BG280 assume plumbed correctly, -10 to the pump, -8 to the regulator.

overkill is not a bad thing with a fuel pump....... the Magnafuel 500 is a damn fine pump and you'll have plenty of room to grow with it.

I wouldn't use a BG anything if he gave me the whole friggen place...... I use a aeromotive 1000 and four port return regulatorwith # 10 to and from the pump and #8 to the carb, used 2 holley 110 (blue) with no bypasses in pumps total flow of 330 worked for years

Being that I already have a holley blue on the car, don't think I haven't already considered adding a second . BG no longer has the whole friggen place, the bank took it. From what I hear, Holley bought the rights to the product line. The reason I am considering BG products is because a member here has a pump for sale and I have connections with former employees for repairs/parts.

add another Blue and then if it's not big enough you can change it, but if you have one on there allready good place to start

Were you piggybacking or duel feed lines?

side by side 2 # 8 going into the pumps and 2 #8 coming out and going into #10 to the front and back,#8 to carbs, worked for 10 years or more

IMO get a prostar 500, if you go bigger later your set. The 500 has a filter built in so that eliminates that also.
