For a baseline comparison, my Dad used to get 9 or 10 with his 455 cu. in. 442 Olds. My friend who has a Dodge Ram with the 5.9L 360 (2002) gets 8 or 9 (city). But trucks are geared differently or higher than cars right? I could squeeze 12 out of my 383 Charger. I would guess not much worse than this. Oh, I'm getting 19 or 20 city (winter!)
thanks, I'm hoping the torque advantage will far outweigh the mileage disadvantge. I kinda figured I'd be able to pass everything but the gas station. Should be fun though
in the attachment, you will find my gas mileage for the last year. I keep a book on getting gas. The most right list shows you the mileage per 100 km - you will have to convert this, since it is Liters for 100 km. It does convert to miles per gallon somehow. 20 miles per gallon is about 9-10 liter per 100 km.
The mileage is for the stock vehicle, running a 472 engine on the TH400 3 speed A/T, with 1" carb spacer and flowmaster muffler. Other than that, its stock, but the carb seems to be somewhat out of tune. I mostly cruise at 55 to 65 mph.
