You would be amazed how strong the factory clutch is.
Mine with stood a 150shot, 26X11.5 MT ET streets and 5500RPM launches (1.60 60fts) for a couple of months before it finally gave up.
If your under 450HP and on real street tires, a good quality stock replacement clutch (like a LUK or SACHS) will be fine.
If you just have to have aftermarket I would suggest a SPEC Stage 2. I have the stage 3 in my car currently and its been very good but its a nightmare to drive in DC traffic.

fror a between stock and racing clutch, I recommend going to carolina clutch. For a pull type clutch there is only one source of the pressure plate (valeo)...thus the only thing you can do is to get a more agressive friction material and lighten the flywheel.
Don't even waste your time with the Mcleod, Spec, or others if you are going to go with a single pull type clutch. A "stage III" iron disk clutch is worth about 500-600 hp with out worries.
If you are willing to convert to a push type clutch or twin disk; then these aftermarket companies start to have products that are worth their price. The real key (and pain in the ***) is the hydraulics. Most rely on new slip on throw-out bearings...most have runs where the hydraulis are not up to snuff.
I'm using a pull twin from mcleod...many because it took me 3 tries to get a work master/slave and I am not willing to give them up.
i went with a kit from Carolina Clutches.. stage II and a 1 peice steel flywheel.
i have no complaints at all. it's very friendly on the street, and has been holding up well all around.
Honestly, it acts like a 6 puck sinstered bronze friction disk clutch should act like. It is very "grabby". Even when cold it wants to lock up as soon as you touch the pressure plate to the disk. If you hold it in between and force it to slip it chatters and jumps. Once you slip it enough to get it hot, it refuses to slip at all and tries to lock up like it was completely out, acting more like an on/off switch than a clutch.... althou it takes a little while to get it that hot.
It's not THAT big of a deal, Requires a lot of attention to drive the car properly in traffic. You just have to "roll it out" easy and keep the RPMs down on take off to aviod burning the flywheel and clutch disk up.
Like I said I love the clutch. It's great at the track and its fine for a nice drive around town or in the country. However it is a nightmare when you have sit there in a 6 lane parking lot, stop and go for 1.5-2 hrs to make it home (12 miles away) everyday.

thanks for the reply, I mis-read your post the first time thinking you had a stage 2 vice 3. I'm leaning toward the stage 2 for my project, which should have a little better street manners.
I have a mostly stock 92 LT1, has roller rocks and headers. I installed a new dual mass flywheel and stock clutch about 5 years ago. I put 2 years of autocrossing on it and she is still doing just fine. The only reason you need to upgrade the clutch is if you plan on using slicks and heading down the 1/4 mile. Don't forget, when you go with a single mass flywheel, your tranny will sound like it has rocks rolling around inside at idle.
