I need gears bad, I still am running the stock 4.62s rear end gears.
I was going to swap over to some 5.12s out of a man trans equiped
kick but they crushed the car before I could get them out

5.12s aren't low enough anyway, it would be about the same as you
driving in 4th all time as the auto trans is a 1:1 final drive ratio.
the high point is that the 5.83s will put the gears ratios with 33"
rubber to the same (aprox) as stock with 205 tires !!
I have a set of street rubber that I run to keep from chewing up
the swampers, I run a set of 31x10.5s most of the time, as far as
top speed, remember I'm Turbo Charged!!, not much of a factor.
I got plenty of go, gears will just make it better, really I'm more worried
about the trans and the extra stress the big tires put on it, I have
250K miles on it and it's never been rebuilt.
A friend of mine was following me here in the mountains, he's got a
Tracker 16V, he was on 215 tires and was having to work it
hard to stay up with me running the 33s, so a little lower gears and I
will fly along in the mountains.
