This thread is awesome from the point that engine owner ended up with something not as anticipated to a builder/machinist saying "let me help" and other members willing to provide needed parts. You just have to appreciate and respect the community.
My curiosity has led me to ask the builder/machinist, when all done and ready to return to owner do you plan to dyno and if so I'm sure a video will be shared?
Thank you for your willingness to help another and sharing with everyone. Kudos to you.
