Gas Mileage query Holley 318

Uhhh, what? The Holley operates on the same principles and physics as any other carb. It is affected the exact same by atmospheric changes as any other carb.

So you buy what is built as a performance carb and the you complain that it’s harder to tune than a carb was designed for emissions and fuel economy? That doesn’t make sense.

The Holley (I only use clones I will not buy a Holley) will do everything a Carterbrock will do and make more power doing it.

I'll admit I have very little experience messing with Holley-style carbs. So it is possible to tune a DP-type carb for good mileage without sacrificing throttle response? I was under the impression it was pretty difficult to have both. I want a DP on my car because it is more tunable and there's no delay from waiting for a secondary air door to open up but again I haven't messed with one yet myself, I don't know. I did test an old Mighty Demon years ago but it was a "race" carb with no choke, PCV or vacuum ports so I sold it before I tried tuning it. Also did an initial setup on a 770 Street Avenger (vac secondary) for my cousin years ago but never got to drive and tune it to run its best as the car was basically a roller with a 440 in it.
