it is a really easy swap in that year of a truck. i did one in a 92 with a 6.0. if your good with wiring it will be cake. you can even use all the stock gauges other than the tach. if you get into it i can help you out alot with it. i have a lot of pics on my myspace of the build.

sorry for the delay. yes you can have heat and ac. heat is an east hook up. on the ac if you want it you will have to get a different mount to it puts it out board on the motor cause where it is mounted factory on the motor it will hit the crossmember under the engine. on my swap we used a howell harness with a 4l60 behind it. the harness has a ground, fuel pump, and two ignition wires to hook up just to make it run. thats it. simple. theres a couple other wires for tach and speedo. if your truck is bagged and lays frame you will need to change the oil pan to a camaro oil pan. summitt sales a whole changeover kit for 180. what tranny are you planning on using. for a fuel pump you can go to parts store and just pick up a pump for a 96 and up vortec motor and it will drop in and mount in your sending unit that you have now. and make sure you change the short rubber hose from the pump to out the top of the unit. cause your tbi motor is low psi and the new pump is higher and it will blow it apart. learned the hard way when forgot to do that. you may be able to use the tahoe throttle cable. theres not anything else i can think of at this moment. anothere website to check out is ls1truck.com it has a swap section. very helpful.
my 4 door was built and havent figured how it was vin'd. but it passes. lol i bought it built in that configuration. it has a suburban frame under back to the center of the rear doors and then welded a truck clip to it. all mounts lined up like factory. now what makes mine screwy is the cab come off a hd truck cause of the cab lights and gauge cluster was a diesel cluster. but it was vin'd as a 97 ext cab. and not a thing on that truck was 97. lol butit all passed inspections. anything else let me know
