Do you know what your MPH would be with your existing gears at your red line?
Great Suggestions

I be happy reaching 190 mph, I have to look to see what MPH yellow-bird top end was, and then I need to find the someone to help me with the calculations
I know I have run 142MPH on the 1/4 mile at the end of 4 th gear at 7800rpm if thats of any help
