couple more things I found out :idea:
in 94 and i think 95 they made 200hp with a cpi fuel injected 4.3. whereas the regular 4.3 made 150 or so hp. in 96 the cpi engine was dropped and the SS and reg. s10's made around 180hp. the new Xtreme's make 185 i think.
they also came with a 3.42 locking rear-end, and before the zq8, they had heavy duty shocks and thicker front swaybars. they also had a special centercap on the wheel, and came with BFG comp t/a's. The grill was painted the color of the truck, which it wasn't on reg. s10's. and it had driving lights in a SS only valance, and special badging.
Thats all I can remember, and I'm not sure its all right
cause I didn't have the $$$ to buy the book at barnes&nobles, so I tried to memorize everything i could

lol
I'm sure someone else could give you more info about the 96+ SS's
