What would happen if you swap the engine over and just swap the ls6 on to the 98? I know the cams are different, but how would this affect how it ran?? would it misfire at idle without the proper tune?

If you want to swap the whole engine harness as well I think you'll have some rewiring to do on the connectors by the PCM. Not the actual PCM connectors (which will be different from 98 and the other years) but the ones that connect the engine harness to the body harness on the passenger side of the engine bay.
