I'm sorry Alex, I forgot to give my answer in the form of a question. <g>

Actually, that was my way of agreeing with your opinion.  I also think that
4.10s are a good ratio for street driving with 35" tires.

For some reason, my tach reads a bit lower at that speed although you'd
figure it should be the same (3-spd auto with 1:1 drive).  I read the speed
off my GPS since my speedo gear is way off.
