14mins-Thanks for the information on the dyno numbers and it looks like different dynos will vary greatly so i will just have to see how it performs when i get it back.Sandman430-The black raptor that i am talking about is from albany( i think)and my motor is being assembled by the same builder that did his so it should perform and hold up well.A friend of mine has a 39 mm fcr for the 400 ex that is almost new that he wants to get rid of if you are interested i can ask about a price and let you know.
