On the road cruising on light throttle pressures at or below 2500 RPM between 12.0 t0 15.0 MPG, around town depending on how your driving 6 to 10 MPG

It is a hot rod, I don't care what millage it gets. LOL My 440, fuel injected 6 Pac, 4:10 and Passion 4sp overdrive gets 11.2 mpg if I drive her gingerly. Real world every day driving is less than 10 mpg.

Filling the tank and doing basic calculations isn't too accurate. TIA. It's a heck of a lot more accurate than any guess you'll get here. Why do you think it's not accurate?

Some good real world info here. I was leaning toward about 8 mpg. I'm only saying that because the gas needle moves like a clock's second hand! Anyone come across magazine specs?

Back in the early 70s fuel mileage wasn't a big issue, but horse power ratings where.
Someone may have an old add or dealer ProMo that listed MPGs.

As an addendum I'm taching 3,000rpm at 60 mph. I'd be thrilled with any mileage in the double digits! And I drive it like I had an egg under the go pedal. (Not all the time though. It is a Mopar!) Put a vacuum gauge in it. If it shows double digits at cruise, it should be dd mpg. Hook up your vacuum advance. Anything that will increase cruise vacuum helps MPG. Kevin

Matters if you take long trips. Otherwise, for the weekend occasional day trip/ride shouldn't matter. Are you planning on taking the car on a long trip in the near future? Is that why you want to get an MPG estimate?

The trip odometer quit working on my truck about mid summer last year. Does you car still have a functioning odometer? Record the miles when you fill up, record the miles when you fill up the next time, and subtract the little number from the big number. Then divide that by the amount of gas you have added since the last fill up. the only way that is not accurate is if you didn't stop filling it at the same point each time. If you don't add any gas after the automatic shut off on the pump shuts off (buy the gas from the same pump from the same direction, at the same angle), you will be very close to getting the same fill each time.
I keep a little note book and a pen in the glove box to record the miles from the fast fill up. I can tell you pretty close how much gas its going to take to fill my truck up each time, based on the miles, and if it was all city, 1/2 city, or all highway driven. Any big block Mopar I ever had was between 8 mpg and 12mpg (that 12 was all highway).
