what MPG do you average city/Highway?
« on: April 08, 2014 - 10:10:30 PM »
Wanted to hear how some have done on their Highway MPG. City is just too variable.   :burnout:
What set up if you'd like to tell us as well that you have.

Strong 340 (the only thing stock is the X heads) with 3.23 gears. Generally get 16-17 overall.
In search of the eternal buzz!

My dad would ask that question about my dodge 4x4.  :smilielol:

MPG is not a question in my book for a mopar. Just drive the darn thing and stop at every gas station while doing so.  :bigsmile:

I agree. I didn't buy this car for fuel mileage, but it's nice to know and let others know that you can have both performance and some economy! My old set up 440/727 got 10 MPG's . I almost doubled that with the new combo and 2X's the power too! Neil was a big help when I was building my engine. He has a sticky about a combo he built that gets slightly better fuel mileage too! :2thumbs:

I have to consider fuel economy when we pay almost 9 bucks for a gallon here in Sweden. Hopefully going from 2.76 to 3.55 for my rear axle this summer is not gonna get the consumption up too much. I wanna drive a lot. Getting about 18 MPG now, 340/727, pretty good.

Big inch Hemi in an "A" body. Just a shade north of 800 HP on pump gas. 3800 converter, 4:10 rear gear, and 31 inch tall rear tires. I get a tick over 10 mpg while cruising at 55-60 mph. And I love the way it sounds doing it.....    :grinyes:

Hey Brad,

what would you get with your set up if you didn't have an OD

 Hard to say? I got 9-10 MPG's with my old 440/727 same 3:55 rear gear ratio?

The ugly truth is I get 10-11 hiway with what I consider a mild build.

I remember seeing somewhere that in 1970, a 440 was rated at 13 MPG hiway, so I don't feel too bad. I just wish gas was 50 cents a gallon like back then.   :grinyes:

Best I've managed in my 74 satellite with a 318 is 27 mpg on the hwy.  :bigsmile:

After I build the motor I am hoping that I might still see 20 on the hwy.
