For this engine I still like the McCulloch. They were made to blow through carbs. Here is a list of venders. John Erb in Carson City, Nevada might be able to help. The info here is not current. John no longer works for Silvolite pistons. He makes lots of Studebaker speed parts. He might help with piston ideas and cam grinds that work with his souped up superchargers. He is a busy guy so things don't happen really fast but he knows his stuff.
