Hello everyone.
Im not sure if anyone could answer this but I might be getting a 1983 Camaro with a 355ci small block. The engine was rebuilt 25k ago. I was just wondering what the gas mileage is like on one of those.

 

More than 10 less than 20mpg... That's a very broad question. Transmission, axle gear, and about 900000 more things will affect how much fuel it eats.

Hopefully it runs well for you, goodluck!

 

I have the same exact car with a built 355, t-5 trans, 3.73 rear gear and 28in diameter tires and i get about 12city/18highway hope this helps
