Who's running 4:11's?

[Tony_SS]

What transmission are you using? Or is it not realistic to match 4:11s and 2500 at 75mph?

What size tire? Hmmm I'll have to check my tach and speedo.

EDIT:

Found the info:

Transmission: 6-Speed Manual
1st Gear Ratio: 2.66:1
2nd Gear Ratio: 1.78:1
3rd Gear Ratio: 1.30:1
4th Gear Ratio: 1.00:1
5th Gear Ratio: 0.74:1
6th Gear Ratio: 0.50:1
Reverse Ratio: 2.90:1
Final Drive Ratio: 3.42:1

My trans has the .50 6th gear.

27" tire if that helps. Edit--- 2200 at 70mph, my bad, I should drive the car more, I'd remember this! (Which makes me wonder how fast I was going to carlisle at 2400-2500??, I never paid much attention, the top of the speedo hides behind the wheel!)
