Gas price going up // Rethinking the new project car

Years ago a guy did a 5.9 swap into a Duster using the OEM EFI and claimed to get 25 mpg. I know it was a 4 speed because the thread was about turning the 143T flywheel down to use a 130T ring, but I don't remember if it was an A833OD or not.

Either way, if true, even a stock 5.9 might not be a bad option if that's what you have.
