Your biggest challenge will be tearing out the old engine management system and installing the new one. The airbag controller will not be happy when you remove the old PCM. I have no idea whether it would work with the LS1 PCM if you threw it onto the class 2 bus. It's entirely possible that it would. My air bag light is on now, but the 95s used a different data bus than the OBDII trucks.
Fuel system is already in place for you in terms of a suitable pump. You'll have to do motor mount adapters and work out AC, by notching the frame, getting the S&P kit, or building your own bracketry. Also depending on the mounts you use, may need to alter driveshaft length. Will need to get a 99+ transmission. Will need custom exhaust and air intake of course.
Wiring will certainly be the biggest challenge.
