'64 dart sedan - 225 /6 bored .030 over, headers, 4bbl carb, 3-speed 904. Engine's built for mid-range power. Previous engine had no power once I was trying to go freeway speeds. Could barely get above 65, so worked to fix that.
Averaging 18-20mpg
I do mostly freeway miles around 70mph. I use an app to track mileage at fill up, and how much gas I put in. Then the next time I refuel I put in that mileage and how much gas I put in. It then calculates how much gas was used and how many miles travelled. If I had time and money I'd play around with tunes and driving styles to figure out how to get the fuel efficiency higher but I'll settle for what I've got. That's with a 160º thermostat too, The 180º and 195º just ran too hot for comfort personally. If I had an electric fan that could run full speed at idle, I'd go with one of those, but even with the 160º, if I get stopped in traffic for too long it'll creep up.
