I havent read any " other" posts, just this one, but one thing clearly comes to mind. You would best be advised, to go speak with a competent engine builder in your area, and sit down, one on one, and develop a PLAN, based on his EXPERIENCE as a builder. Your questions are all over the place, and your trying to justify building the engine based on magazine articles, internet builds and so forth. I understand, its easy to ask questions on the forums, internet and such, but all you will do, if your not experienced in building an engine ( in this case, you admitted you dont know anything about strokers) is end up with a bad build your not happy with, and wasted a lot of time and money. Find someone to work with, and all of this will go away, and you'll be happy with a engine you can drive, race, and enjoy. Most people go off center, when they arent realistic with both their needs, and reality and budgets.. A good builder can get you on course there. Good luck with the project.
