Thanks. We're going to a new track tomorrow and the motor was on a dyno It just seemed weird that it make peak Hp @ 4700 I thought something was wrong. It does make nice steady power from 3.8k-4.7. I'll watch how much we loose it the corners but from the paperwork I don't think I'm gonna spin it much past 5k based on the print out. We never raced a flathead though, just clones on a 1/10 mile. Well see how it goes, thanks brian.
