A Gen2 with 4.62s and 33" tires will be turning 2128rpm @ 60mph ground speed in overdrive.

Various inaccuracies with the factory speedo and/or tach may show otherwise.

So, I guess the SR has lower transmission gears?

Not to the best of my knowledge.

I used the following gear ratios and information in my calculations, feel free to correct me if i've been misinformed:

33" tires
1:1 t-case ratio (assuming you're not rolling down the highway in 4lo)
4.63 differentials

Trans ratios:
2.804
1.531
1
0.754
