MPG Motor Magnum vs. Hemi

Nice going with the Magnum swap, with the EFI you should definitely see some MPG improvements even including a cam and EQ heads (current route I'm going for with a 5.9L in my Duster but it'll be carb'd).

@mgoblue9798 that was the 1st-gen Dak right? Those things are tiny compared to a '94-02 Ram, or an old C-body... would love to get my hands on one with a 5-speed. Or swap a 5.2L into my '93 XJ Cherokee lol.

Major issue with mileage from these motors was they were only used in trucks. There is a guy on Moparts Polara something or another that did a 5.2 swap in a c body and was getting 25mpg. The trucks have the aeordynamics of a brick. I have a 5.9 in a 2002 ram high top van that gets 11mpg. This is after a rebuild with EQ heads, a small Hughes cam, and Magnaflow high flow cat and exhaust. Got the same 11mpg before the build. Point is mileage has a LOT to do with what the engine is in.
