    I had a 2whl drive blazer, 350 + 373 gears. I built a motor for it stock heads, quadajet carb and a 260 comp cam. Milage was not as good as 16 but I think it was pretty close. It would tow my buddies ski boat great.

    My buddie with the boat had an older blazer that we put together the same motor trany package except it had an aluminum intake,Edelbrock carb that was recommended for the motor/intake, the same 260 comp grind and 3.08 gears

    He drove to Palm springs with the boat behind him and got close to 16.. but he was going 70... Tried to keep the motor around 2000RPM max

    To get milage on the highway. Drive the speed limit and use the cruise. My 2007 F150 gets decent milage if I do that.

    ???????????? 16 MPG on a SBC in a step-side????? Heres mine: I have a 1975 Chevy 4X4 w/ a 350 bone stock except for headers, edlebrock int/carb. It has 97,000 miles & has a 4SPEED..... this truck is a lifted step-side....

    On a good day, it gets 10 miles to the gallon. On a bad day, it gets 10 miles a gallon. When I stuff my foot onto it all the time, it gets 10 miles to the gallon. When I go up hill & down the hill, it gets 10 miles to the gallon. I am pretty sure if any one of you drove it, it would get about 10 miles to the gallon.

    16MPG is not bad for a full size chevy truck, they are nortious for getting crappy gas milage anyway.

    A high flow cotton air filter like a K/N, 2 barrel carb & highway gears would be my first thought.

    Keep your tires aired up to the MAX setting, always.

    Do you have a overdrive trans? If not put one in.

    Snythetic oil in the engine, trans and rearend is worth a few.


    I'd also stick a giant vacuum gauge on the dash and drive to maintain the higest vacuum at all times.


    Goodluck, Cp
