I have a 410 stroker with dual quads. 20 miles each way and 4 passes down the 1/4 mile... Took 6 gallons..
My compression is a wee bit to high for pump gas and I like to mix up my own potion. I'm going to take my first long trip soon, 60 Mi each way LOL I'll likely bring a 5 gallon can of pre mix, but I'm very curious to see mileage at mostly freeway speed...
