Looking for better fuel milage

At present I'm only getting 8 mpg in town and 10-11 on the highway with the rpm's never over 3000 and only on the front two barrels. Carb is a Quick Fuel 650 double pumper. I'm running 66 jets in the front and was thinking about putting a plug in where the power valve is to see if it gets any better. Engine is a 360 +.060 with dished pistons in the hole so compression is around 8-9

Car runs great but likes gas. My setup is comp XE 284 with roller rockers and flat tappets. An Eddy air gap intake and Eddy Perf. RPM heads. I have a 3.55
out back with a 2800-3200 convertor.

The 'Cuda is a cruiser with a 99 % of the time.

Any info would be appreciated. Gonna do The Power Tour with it in June so I wanted a few more mpg if I can squeeze it out of it.


Tony I know you like the sound of that cam but that is where your mileage is going. Theirs better cams for your motor witch would make it run better respond better and give you better mileage. I think your cam starts working at 3000 rpm. (Sucks fuel) You can still have a great sounding cam with better mileage. 340 cams sound very tuff. Gear will help a lot.
