It will detinate with out 93 octane gas and im lucky if it gets 10 mpg even on the high way.
displacement and "type of ignition" "type of injection" have far less to do with mpg than the following:
weight of the vehicle (heavy = more gas)
torque converter (old type that doesnt lock up = your gas goes down the drain)
so a heavy station wagon with a non-lockup converter, even with a 318 is going to get crap mileage.
you need a manual trans or a lockup converter.
a manual trans w/overdrive or automatic with lockup & overdrive will do a lot for you. spending $1000's on special stuff to put in a modern hemi is kind of going in the wrong direction to fix the problem.
