Custom built (horsepower innovations)Holley 950 HP carb. MSD 6530 programmable ignition. I'm trying to size a fuel cell, there are enough E85 stations within a 100 mile radius, a 10 gallon will fit the best, and still provide me with enough range. I'm hoping for 15mpg highway.
I think 15-16 may be your high end for highway mileage. Really depends on your driving style. If you can Lean it out under light load highway driving and still keep drivability, you'll get pretty good mileage out of it.
