I had 3.42's in my car and now have 4.11. Obviously the speedo is off. I was curious if anyone knew in 6th gear on the freeway if the speedo reads 80 how much slower I am actually going? Am I actually going 70 or 65 etc.. when the speedo reads 80 in 6th gear?

Thanks

80-82 in 6th, you should be running at about 2200rpms.....

So with 4.11's in 6th I should be running 80-82 MPH around 2200 cool, thank you for your help :-)
