I have always had double pumpers and have never had a problem on the street at all. Put milder accelerator cams in the front and rear if it is coming on too hard. That will help the tip-in/tip-out if you feel it is too jerky. You can also change the squirter size, but for a 427, that shouldn't be an issue. Is it set-up for 4 bbl idle?

Bingo X 2.
Keep your foot out of the DP and the mileage will be about the same if you tune the DP for street use and not top end.
