Nice upgrade. Someday may have to do something like that to mine.

go to the Westcoastcorvette.com web site, and scroll through their "scrapbook" section. They have a chart of various gears at various speeds for c5's and Z06 trannys, auto and 6sp.

I am guessing it would be around 1800 -1900 RPm though. I usually cruise down the road at 70-75 and run around 1700-1800 rpm in mine.
I have to agree. Best mod that I have ever done to the car and well worth the money

4.10's should have come stock in this car. I agree that 80 mph is around 2100 rpms......and on my 500 mile round trip to Vegas a couple of weeks ago I averaged 24.9 mpg. Most of the trip was between 80 and 90.....but there were one or two "simulated" runs to 150 (kph or mph...can't remember

I'm still breaking in my 3:90's installed last week, but I can tell you, it feels like the car lost 500 lbs - I cannot believe how much more powerful it feels. I should have track times on 2-19-06.
