That's impressive but doubt it makes 500 HP. Why less than 2k in miles a year? One of the main reasons I started this was because many people are deterred from driving their pride an joy because of the abysmal mileage. J.Rob
Between the state of tune, carb and ignition, the next mileage getter is your friend overdrive. Figuring where to land the cruise rpm’s (tire size and gear ratio combination) are the final hurdle.
This is the difficult parts since knowing how efficient the engine is without a dyno test can cause a long and expensive search.
