440 engine mile per gallon?

[roger01]

just curious to what you guys are getting ,....mines a stock 440...4bbl.......im getting 12.5 miles to gallon ....i think i need a tune up

[69chargeryeehaa]

i was getting 10, on a good day!!!   i sold my charger, i could'nt take the $100 for a cruise every night.   I had hedders, cam, intake, 750 carb, otherwise stock.

boss's superbird (stock 440+6) gets 28mpg highway with a stock mopar OD 4-speed and a 3.45 Dana

[roger01]

28!!!!...whats his secret

[Mike DC]

The lack of wind resistance probably doesn't hurt.

i get around 7 city and around 11 highway with a stout 440.  runs 13.05 at 105 with 3.23's in the rear

[Rolling_Thunder]

28!!!!...whats his secret

mild gearing, aerodynamics, and most importantly the OD 4-speed and the six pack...         just for laughs we swapped the six pack set up onto his 68 GTX convertible and drove it and recorded a best of 25mpg...    his GTX has the 3.54 dana with 26" tall tires. We then swapped the entire engine combo into his superbird...     and recorded 28mpg...     so the aerodynamics make a 3mph difference....     

The secret ?  the OD trans keeps the RPMs low...    necessitating only the center carb's operation...   so you are cruising on a 350cfm 2bbl....

I put 2 600 edlebrocks on my car and am trying to get it where I can drive it. If I go for a test drive and come back the gas hand moves. I think its about 4mpg right now

"You want make gas mileage  with 440?  Ha ha ha!  Everybody know, 440 is only for hitting gypsies!"

I took my 10.5:1 edel. headed 440 6 pack, 4 speed, 3.54:1 69 charger on a 600 mile rod run last weekend.  Some stop and go in small towns, speeds between 60-75 mph.  I averaged 13-14 mpg and was pretty proud of that.

[george68hemirr]

i get 6 miles to the gallon on my 572 hemi with 2 10.50 dominators if i just putt around without jumping into it.....when you have a mopar who cares about gas mileage....just have fun and buy a gas station...HAHA!!!!!!!!!

I hate to say it but your boss is pulling your leg. A 3rd gen Charger (which is far more aerodynamic than a Daytona) with a 318 and 2.76 gears would have trouble reaching those numbers.

My Dad's bone stock 66 Chrysler 300, 2 dr hardtop is currenlty getting 16mpg cruising on PA Turnpike on the way to Chrysler at Carisle.

[pandamarie]

My 70 challenger 440 six pack gets 17 on the freeway going up hill to Reno from Sacramento but thats keeping it a 65mph or under which is hard to do. I do put the heavy springs in the outer vacuum pods for long trips and switch them when I get there. the 69 charger gets 8 in town and 10 on the freeway, will let you know if it changes once I finish converting it into a Daytona.

[Mike DC]

   440 motors and gas mileage . . . heh, heh, heh . . .

I've witnessed it first-hand  (I was driving)   keep in mind that a 3.45 with a factory OD is higher (lower number) than a 2.76...      the six pack allows only the center 350cfm carb to be used when cruising...      and a superbird is pretty aerodynamic...    dont know how good compared to a 3rd gen...        but honestly...   28mpg - - -   put your foot into it once and a while around town and it is getting around 11mpg...

when i had the stock bore and stroke 440+6 with a .480 lift and adv. 292 duration cam in my 1970 challenger with a 1800-2000 stall speed convertor and 3.55 gears along with 15 inch tires. i got 12 mpg on the highway running 55 mph and around 8-9 mpg in town.

[gordo1968charger]

if you get more than 10mpg,your not driving it correctly!lol.

[Yeahmate]

Hate to say it, but you brought the wrong car if your worried about the cost of gas or tyres. 

[Musicman]

I think it's safe to say that 12.5 is a pretty good average for a stock 440 4bbl.
