Small Block Stroker ... Gas mileage?

I can get 17+(55-75mph) out of mine, E-body 3.23's 727 and 26" tires. Car weighs 3710lbs w/me in it. Running a 770 Holley Street Avenger Crane 302-2 Hyd cam Air Gap with Doug's headers to a 2.5"h-pipe exhaust. I run 89 octane most of the time now. I'm told I can run 87 but haven't had the balls to do so yet.... I'm running Mildly Ported Iron Heads(587).

Car runs 12.7's @ 109+ or so in the 1/4 mile spinning hard to a 1.9x 60'.

I bet with some easy cruising at 55mph it would have been better.
