My 74 Duster360, still has the original 360 in it, with one rebuild on it. All stock for 74, including the cast iron 4bbl intake and TQ. 727 with factory stall convertor (believe it is 2800rpm), and have changed out the 8.25 rear end with sure grip and 3.55:1 to 8.25 open with 2.45:1 ! - why you ask ???

In 1999 I drove to Carlisle and back (sheesh, like over 3,400 miles round trip ??) . . wanted some mpg and keep the RPM down while cruising . . . here are the REAL world numbers for my car - 70mph all day long, 2600rpm and 22MPG !!! Not to mention LOADS of mid-top range power - gotta love passing in this car !!! . . .

I think if you did a rebuild of the 360, with the 340 cam, used the TQ, had a bit of stall convertor and kept your gears you have now, you would be happy camper !

Those US or Imperial gallons, cause if they are Imperial gallons that mileage is horrible. For those that don't know, Imperial gallons are 5 qts, US are 4.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
