Springs, LT1 K-Member, I just woke up but thats all that comes to mind right now. Springs because yours are not for the heavier motor setup, get all 4. The 3rd Gen sites sell the LT1 K-Member for what you're doing. Tubular, and pricey :\
If you want near the same power (Unless you already have the LT1) a TPI motor would rock. I miss mine :\

If it uses a 700R4, you shouldn't need a new crossmember, but I don't know what they dropped in the V6 models. I assume a 700 w/ a different bellhousing for the V6 pattern, but I guess it always could be a 200R4. If it isn't a 700R4, you'll need a new crossmember. You'll want the bigger swaybars as well

Oh, if you plan to use a 700R4, for ease of use make sure you get a 93 LT1. Otherwise, you'll need a 94 or newer 4L60E for it to work. (Or some tranny simulator box for the ECM)

You don't need an LT1 K-Member. The stock 3rd gen one will work fine. I'd recomment a tubular one for weight savings and strength. If you're gonna go with a T56 6-speed, you'll need a different tranny mount. I used the Spohn one. If you're going with the 6-speed, you'll need the 4th gen clutch hydraulics as well. If you check out thirdgen.org there's plenty of information over there about this setup. I did mine about 2 years ago, my memory about the details isn't very good.

engine wiring harness maybe to convert over,
convert to speed density system so you can plumb the intake better, uh, thats all the things that pop into my mind besides what the other replys have said,
but definitely find a conversion wiring harness
