I had a double pumper on my 68 GTO. High compression, solid lifters, single plane, ran great, got 6 miles to the gallon. Swapped it for a Q-jet and a dual plane, ran great, got 14 MPG.
My 428 in the Firebird gets 14 mpg on this island, I get 22 mpg on the highway at 80mph, but a lot of that is due to the fifth gear, I suspect it would get better mileage with a Q jet.
Don't know but suspect.
