MPG Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mholmes · 09-29-2007, 04:27 PM

I've got an '82 Scottsdale 4X4 that I just dropped a new stock 350 engine from JEGS into. This one is rated at 260 HP. Also with the kit I got the Edlebrock 650 CFM carb. Truck has the 700R4 transmission in it also. I'm in process of replacing the gauges as I broke off 2 of the needles when I was putting in a new circuit board trying to determine why gauges don't work. Anyway, what kind of MPG should I expect with the new engine. I've gone through about 4 tanks of gas with the new engine and I'm guessing I'm getting about 8-10 MPG. I'm waiting on a new speedo to compliment the new engine so I can't be precise but I was thinking I could expect around 14-16???? Am I expecting too much?
