Without knowing anything about your car it is impossible to say. That may be really good and it may be really bad.

My 99 gets about 16 - 18 around town and about 26 - 28 on highway.
My 67 gets about 5 around town and about 7 on the highway.

Once you finish exploring the power and performance your new LS1 provides you will probably get better mileage.

I got 17-18 (and worse) mpg's, but now I've average out in the 20.1-20.9 mpg's most of the time. I've gotten as much as 26.
