The Stovebolt Site Forums The Shop Area General Truck Talk Realistic Speeds and gas milage for T-5 bolts???

I wouldn't expect more than 21 to 22 mph. For the 302 gmc I am building, I'm not expecting more than 17 mpg, and I'm hoping I won't be getting less than 13. Advance Design trucks aren't known for there aero dynamics. Better than Task Force trucks I suppose.
