Loosing gas fast...

Hi,
My '72 Chevelle 400sbc .030 over and 435hp. At least that is what I was told when buying the car. Now, I know muscle cars weren't supposed to get good gas mileage, but my car still shouldn't be drinking gas like it is now. I have to newly rebuilt qjet on it and runs great. When the car is running, the needle in the gas gauge just keeps on moving. This happens when in "park" or "drive". It doesn't really matter. I was going to change the rear end out of it, but I don't have the garage to do it in. What can I do to get alittle better gas mileage?

Thanks,
Ethan

Scott,
It was probably pointless of me to of typed this topic. I'm only 19, but I do understand these cars weren't made for good mpg like the cars are today. I love my car very much and was just wondering if there were any other ways to get ALITTLE better gas mileage. I can't answer what base and total timing is, since I don't have a timing light nor do I know how to use it. I think I have vacuum advance on the distributor. Is it just a little vacuum pod coming off the dist. that connect to the carb? I'm sorry, I'm not sure. I'm not sure about the metering rods either. I'm not sure about the stall converter either, sorry. The last time I heard about what my car gets mpg wise, was 4.5-6 mpg.

Can you tell me more about an overdrive trans? Mine right now is a TH-350. I need help with tuning the rebuilt Qjet, too. I'll probably buy the timing light here real soon anyways.

Sorry that I don't know more, but I am new at working around engines. My father did it all the time and can only remember little things.

Thanks,
Ethan

Mike,
How do I change from pumped gas to Ethanol?
