This page is devoted to exchanging knowledge about Hercules built engines or any related topics. Much of this information was obtained from research done by Glenn Karch, my thanks to him for his generous contributions. This page is in its infancy and with your help can become a clearing house for information on this topic. If you would like to have your engine pictured on this site please e-mail me to make arrangements for getting the picture or image to me. If you have any information that you think would be relevant to this topic, please e-mail me concerning that as well. I plan to add a lot more information so keep checking back to see what's new. Thanks for visiting this site and I hope you find it useful.
