Richmond 4.10. They were very whiney on deceleration as you can hear in one of my early videos. But now the whine has seemed to go away. I think I'm just about right on the gear. When I ran through the traps at Tulsa I was passing through the traps at around 6800 rpm.
Although I do want to post this question. When I ran the calculator on how fast the top end should be, it said 140+ @ 7200 RPM. When I was at the track I was around 123 mph @ 6800. Now how can that be that 300-400 rpm more would get me into the 140 mph range? Am I thinking that wrong?
