With most engines, increasing compression results in more power, but with a Flathead there is a point not only of diminishing returns, but a point where power is lost--and it's lower than you . The present-day Arduns are CNC-machined using high-grade 356-T6 aluminum, have refined combustion chambers, and improved oiling and valvetrain components. The carbs are the new Stromberg BIG97s, and each flows 250 cfm. Interestingly, part of that room is devoted to engines that went beyond the simple flat-head design and utilized many of the various over-head conversion units that were available.
