When you think trannys also think rear ends cause they're connected. The rear end will limit your overall hiway speed even after you installed that pretty new 4 speed. Here are several sites already discussed on 'the bolt' about determining rear end ratios for the type and gear box you're about to buy. just plug in the boxes and hit the calculate button.
Also consider when you find &/or have built a T5, you may be able to have one built using camaro guts installed into an S-10, depending on your pocket book. Many of us love the T5's and after getting mine built I will not have to worry about pulling a used tranny out to rebuild it... ever. I'm using a 12 bolt 6 lug Chevy 1977 burb rear end w/ 3.43:1, w/ big brakes. Your choices w/ that mid 70's vintage truck rear ends are 3.08, 3.43, 3.73 in 6 lug. There are many other choices. Your choice will be determined by where you live (mts, flat driving roads, hauling, trailer usage, speed & acceleration, etc.)
Have fun
Gooday
