Who cares? You dont buy a classic '78 Regal for the fuel economy, you buy it for the fun. Also, fueleconomy.gov only goes back to 1985.
Good luck.

So basically you want us to guess what your MPG would be with ZERO information on your engine build. You can't be serious.... ...and lol@a turbo at 5PSI burning the gas more efficiently. Sorry man but you offer no information at all, you think 5#'s of boost helps gas mileage. If you're building a turbo motor you don't care about gas mileage. If you're swapping in a V8 you don't care about gas mileage. There is no set mileage for a 305 or 350, some could get 25mpg some could get 8. It's all in the build.

The 305 is a smaller version of the 350 and usually came with a 2 barrel carburetor, so one would think the mileage should be much better than the 350 offered, it wasn't. I'd expect; depending on the rear end gear ratio the car has, that you should be able to get around 16 mpg in the city and maybe 22 mpg or so on the highway

I would guess if it is well taken care of it should get 25-30 mpg if you drive decent. I had a 76 Buick Skylark with a 350 that would get around 25 mpg when I wasn't stompin' on it.

probably better than my crappy 1996 GMC Sonoma which has a 4-cylinder engine in it.
My Sonoma gets a crappy 18 MPG, when it should be getting at least 27 to 30 MPG
