Anybody know what the approx. speed at 5700 is with 3.23's??

5700 with 3.23s
1st: 44
2nd: 83
3rd: 135
4th: 192

60 mph is a hair under 1800 rpm. 75 mph is a little over 2200.

5700 rpm with 4.10s...
1st: 35
2nd: 66
3rd: 106
4th: 152

60 mph is just under 2300 rpm. 75 mph is just over 2800 rpm.

Sounds like you have 3.42?
