Just spent over a week on the dyno with one of these new engines..we tested numerous things from fuel, carbs, timing, valve lash, headers, oils, carb spacers , and spark plugs as well as plug gaps..the list goes on..believe we have a great package for this engine for the 2014 season!! Well see how it stacks up at the world champions against the rebuilt versions..taking orders for these now..304 253 6913..
