Edelbrock 500 vs. 600 cfm fuel milage

RustyRatRod said

Kinda not an answer to my question. I was askin what kinda "difference" do you think would be from the 600 to the 500? In other words, if the 600 gets 15, how much "more" do you think a 500 would get? I bet it's even possible the 500 "could" get less mileage, IF it puts you in the situation to whee you're using "more" of the carburetor, if that makes sense. 15 is pretty good for a big rolling box on wheels.

Gotcha, sorry. My thoughts were that if I used a smaller CFM carb, that I could possibly get a little better fuel milage, whatever it was. Every bit helps, but I understand what you mean about the smaller carb could actually negate any gain expected. I am constantly trying to improve it. I love the snot out of this beast and at times, prefer to drive it over my 2018 Ram.
I'll look into changing the metering rods next.
Thanks!
