idk exact mileage as speedo don't work but my D150 /6 833od gets double what my chevy 1/2 ton 350 auto did! and got bout as much power!!
Doubt they can even get 25. With an od and 2.76 in the real world 16-18 auto stick 18-22Thanks brother!
Ahhhh man! Remember when I first had the /6 in that ‘74 Duster and I was getting 19-ish in the Hwy? The old timers were beating me up on not knowing how to tune the engine and get what they were claiming, 30, 32, 35+ mog’s.
I never believed that **** but! When they were new and the big 3 had mpg Competitions ......
Hell, I get damn near 20 with my 318 and 3:23's. The Dart Lites were rated at 36.Doubt they can even get 25. With an od and 2.76 in the real world 16-18 auto stick 18-22
I get 16-17mpg with my 318 3.55s but it can easily go down to 13 mpg running late to work.Hell, I get damn near 20 with my 318 and 3:23's. The Dart Lites were rated at 36.
Rpm below 2000 is the key.A-body, 225, 904, 3.23, 2bbl Carter with 2-1/4 exhaust. Gets 15-18mpg on road trips with two people and luggage, mostly back roads. Would get higher on the freeway if I kept it at 60 or less, but that never seems to happen. Aerodynamics is a b****.
Rpm below 2000 is the key.
That is correct. But that was brand new while traveling @55 like they did during the mileage contests the Government sponsored. Super tuned and slow going.Hell, I get damn near 20 with my 318 and 3:23's. The Dart Lites were rated at 36.
My Slant running on a good day gets around 18 to 22, w/ Mopar elect. ign., Super Six mod, headers, dual exhaust. 904 Auto. and 3.23 gearset in an 8.75 center chunk. 87 at the pump.

What size tires guys?
25 @ 55mph I bet.I drove to Carlisle in 2017. Filled up right before I got on the Ohio Turnpike and refilled when I got off the PA pike exit in Carlisle. I think it was 320 miles and the last 3 hrs was through a driving rainstorm up and down the PA hills.
1964 Val convertible, top up, 3.23, 7-1/4, 3 speed manual, 195/70 X 14 Kumho radials, fresh and completely rebuilt 225, rebuilt head with pocket porting/gasket match by me, mild Oregon regrind, stock rebuilt BBS, breaker point ignition, about 8* initial timing, 2" single pipe.
I tried to keep it steady at 65 even through the deluge and passed everybody in the rain when the lesser vehicles slowed down.
23.8 MPG on one tank.
I was disappointed when I drove the 6 hrs to Clay City, KY this September but was in a hurry and only got 22 going down. Didn't check going home but it was driving through the remains of a hurricane.
With a wagon? 22? My girlfriend has a wagon 65 valiant she drives slow and never floors it probably five miles under the speed limit she doesn't even get 20mpg maybe 17 at best. Motor and trans rebuilt stock one barrel 3.23 gear in the rear.Best mileage I've recorded is 20.5, that was with me, my teenage son, a mountain bike, and 75 lbs of tools in the car. It was also before I rebuilt the carb, and dialed in the rest of the tune...
I'd be willing to bet that I'd get 22 mpg now with the car similarly loaded. 25 wouldn't be difficult with some real care paid to tune-up, tire pressures, etc.
And this is in a wagon, which has to weigh a few hundred pounds more than a 2-door sedan.
I think 25 mpg should be obtainable by most /6 A-bodies, 30 would be pushing it, and 30+ should be reserved for the best LSD trips.
With a wagon?
