    Just wanted to get a feel on other people's Camaros (stock and mild modified) and what they get as far as MPG. I have had mine about 2 months and only had the opportunity to drive it (2) times locally and it is putting a dent in the wallet.

    Specs:

    1981 Z28
    4spd
    383 Stroker
    mild cam
    Aluminum heads
    Aluminum intake
    Heddman Headers
    2.5" exhaust with flowmasters
    Holley 750 cfm
    3.08
    estimate (best guess based on limited driving) 10 MPG local and 15 MPG Hw on 93 octane.

    I've gotten as good as 17.8mpg and as bad as 7 when it was leaking out a few bad hoses. I've averaged 13 overall but lately the car barely warms up before I park at work so the mileage is terrible.

    18-19 on the HWY at 70, in town don't care really. It's lousy though in town.

    Overdrive is almost a must these days as well as really dialing in the carb or going EFI.

    got gas milage

    love those 2nd gens. my 72 SS396 will be done soon. I expect 15-16 mpg with the 3.42 gear. On the other hand you gota love the LS engines. I built an 01" SS 630 hp 575 tq at the crank 521 hp 475 tq to the ground with an auto. runs high 11's @ 125 gets 20 actual mpg @ 70 with the cruise on and the monsoon blasting. Isn't technology great.

    i'm getting about 10mpg too. i didn't build it to be gas efficient though. my '72 has a 350 with blower, fuel injection, World Sportsman II heads, headers and TH350. don't know the rear gear ratio. i'm planning on putting a 700R4 in the car soon so hopefully the mileage will be a little better.

    I've never tried to even guess on any of my "together" Camaros other than my '69 Z. 302 .060" over with the off road cam, cast iron exhaust, true duals (2 1/2"), single 4bbl, 3.07 rear gears and an M-20 I saw maybe 12mpg on the highway and 10mpg or less in town.

    The change to 3.55 gearing didn't make it change much.

    the change to the crossram and the headers ran it down to about 9mpg highway and something under 7mpg in town

    Of course a heavy foot and no torque under about 3K RPM don't help out much:)

    my 73 with the air on and the 373 rear we're looking at 7 to 10 tops. i know you are trying to fix your air . those early compressors rob anywhere 20 to 30 hp . yours is a little better beacause its a rotary design. mine is a old style harrison. a real power drain but thats not why i had it fixed

    Mine hasn't done much driving the past few years, but it was my daily driver for 17 years. During the time as a daily driver, it delivered 19 mpg all the time on the highway. That was with a stock 300hp/350, Muncie 4 speed, and 3.31 rear gears. The early quadrajets were wonderful carbs.
