U.S. Patent #7,322,750

Over the last fifteen-plus years, as the street / strip hobby has grown to unpredictable dimensions, the venerable production blocks have been used and abused by countless numbers of racers. In the process, there have been more cracked blocks that would fit into a warehouse. As a result, there has been a need for a solution to the cracking problem. Some companies in the aftermarket have chosen to build a bottom-end girdle, which ties all of the main caps together in order to prevent then from moving around under the intense amounts of cylinder pressure that blowers, turbochargers, and nitrous oxide produce. As the pressure builds, the main caps tend to want to assume an oblong shape and “close up”, and Bessel’s Motorsports Splayed Main Cap system puts all of those fears to rest. The ingenious solution has proven its worth in numerous applications, and Bessel Motorsports can build a main cap system for virtually any pushrod motor including most aftermarket blocks. - (RacePages April 2008)
