Given that particular year used an internal slave cylinder much like the F body did, I would bet a LS1 style flywheel/clutch setup will bolt right up and work fine. You might need to shim the slave though.

I used the Sachs 1050 flywheel for an 06 Silverado to mate my TKO to my 5.3.

Depends on the bell housing. Does it currently have a 168 tooth flywheel?
Check out this for flywheel/clutch options.
