Not 100% sure whats involved in a v6-ls1 swap. If it was going to be a race car it wouldn't matter. But I don't want to re do the entire wiring to make everything work. K member, steering gear,brake system might be different between the two I'm really not sure. A v8 car would make things alot easier. 99+ preferably too, I think 98's had some funky wiring.
