I totally forgot to go back and check my project thread at NastyZ28.com:

1978 was the first year for EPA fuel economy ratings. The L6 Camaro with 3spd was rated at 18mpg city and 28mpg highway, with an average of 21mpg and $500 annual fuel cost. I calculated mileage for two fill ups and got 15.6mpg and 16.0mpg for all in town driving. That's with tuning it or a complete exhaust. I will probably have a new low flow exhaust on it in March, along with some ignition upgrades and tune up. I already have a K&N filter on it, and I need to flush the radiator and change the oil too. Then I can do some driving and see what the mileage is then.
