Unless you count the highway ramps, you are right. I thought it was the velocity of the exhaust charge that we are concerned about as far as scavenging but I could be wrong. If so, he might not get the full effects under a certain RPM unless he goes more radical. I would think that he should speak to a builder so he has the right COMBINATION and not fast parts from different combinations since they all need to work together.

I guess I need to ask my son and grandsons, who live in Statesville, why they didn't mention that when I visited for a couple days on my East coast road trip last year. Hmmmm
