Gas Mileage Issues

My 225ci slant six seems to eat up more gas then what i put in it. is there any way i can tweak the mileage and get more out of my money driving it?

What year /6 and size ? are you running point's ? 1 barrel or 2 ? adjustable valve engine ?..
X 10 on the fuel getting to the carb at well over 160 degree's :glasses7:
I moved my fuel line away from the block, removed the point's and the iddie Bitty down pipe, your exhaust (if it is stock) has a 1 7/8 pipe I believe, going to a 2 1/4 exhaust will help tremendously and gain hp.
It's hot under the hood so I put a fresh cool air breather system on and it loves the 100 and lower air :glasses7:
