You mentioned track duty alot do you have an ET goal? at least your going dana from the start also some might want to know the cam timing events / specs to give you a better choice on compression I think the duration @ 50 and intake valve closing ABDC should be balanced with compression choice also so you dont bleed off too much and loosing some free ponies! whats the weight on that thing anyways

here is something for ya to play around with so you get a better feel for it... I would say "about" 9.0 to 1 dynamic is pump gas frendly
