    Well, in theory the Q-Jet with the small primaries and humongous secondaries will get the best mileage. I ran a spreadbore on a 460 in a pickup and got far better fuel mileage then I did with a square bore.....If I kept my leg out of it.... When you get into the secondaries, they don't do well on the mpg at all...but then nothing else does either!!!

    Q-Jets are 750 and 800 cfm. A Q-jet only gives the motor what it can take. I have Q-Jet 750 on my 406 sbc and a Q-Jet 750 on my Buick V6
