There you go ,Pat knows how to do what I am taking about.I understand what needs to be done ,and why,I just do not know how to do it!!! Your job as a engine (customer) is to give the engine (builder) the application specifics so that the( builder,some one like pat) can do what needs to be done to make it happen.You can see how 1 little piece of info ,like only turning 3000 rpm or the fact its going in a air boat changes everything.Comunication is a major key to sucess in anything!!!You need to have all the facts and not "hope" it all turns out well.The engine will only turn out as good as the information you provide the builder!!!!
