MPG Increace

Ok so right not I am working at a Dodge dealership and love it but am having to drive 40 miles a day. Right now I cam getting 8mpg and need some advise to increase MPG's. I know some of you are going to say get another car for that but I don't want to I love my car being my Daily driv
er and cant stand not to drive it.

Right now I have a holley 750 carb 4160
I was think about getting a holley 670 vac sec manual choke square bore. Do you think that would increase MPG's

I also thought about putting duel electric fans for a little less drag on the engine. I would also run a oil cooler.

What other things do you guys think will help
