I have a Holley 750 vacuum secondary on top of an e-performer sitting on my 406 Poncho- I could get 14/16 mpg with a light foot, and this is with 72/80 jets, a TH-350 and a 3.08 posi. The DP's are good for racing but not daily commuting- run vacuum advance on your distributor as well and your fuel economy will improve.
