The prototypes of both engines are going to get a dyno workout- - - -probably on my 16 foot trailer so I can haul it around to reunions, car shows, and homecomings. I believe a 150+ HP "216" might generate enough interest to keep my grandson busy building engines for a few years after I get too old and feeble to do it. The same uber-long stroke modification could be applied to a 261, resulting in a 300+ cubic inch engine that will out-torque anything else remotely resembling a stock stovebolt!
