Good deal about the hammer Neal. I thought we would have to take it away from you, until you learned your lesson
As for the flywheel, are you just wanting to resurface it? Or are you wanting to lighten it? If you just want to re-surface it, any machine shop should know the deal on that. As far as lightening it, I don't have a clue. You might want to leave that up to the guys who do it best, Like a Porsche specialty machine shop. Or, at the very least, someone who has some experience with it.
Does anyone know if these are internally, or externally balanced engines?
