Do I possibly have shorter gears than stock?
I've had my car for a month or so now, and I noticed that my mechanical and digital speedos were reading differently. I've seen as much as a 9mph difference between the two with the digital reading higher. As far as I know the car is stock. So, I asked my buddy who used to have a GTO 6-speed with stock gears about what rpm he was at during cruising speeds. He thinks that mine is geared a good bit shorter than stock. I'm still running the original wheels with 245/45-17 tires. Tell me what you guys think.
These mph readings are off the mechanical speedo
1st gear top speed is 42 mph
6th gear @ 70mph is 2150rpm
6th gear @ 60mph is 1850rpm
The car also blows through 1st and 2nd gear spinning its *** off if I let it.
Thanks, Danny

I'm right at/around 2000 rpm at 80 with my stock gears. Around 2000 going 45 in 4th. Around 2000 going 55 in 5th. Around 2000 going 30-35 in 3rd. Sounds to me that your gears are not stock. Lucky you! I want to get 3.91's
