well the 97-98's did have a BIT more power but not much really. And it was mostly due to the 70mm MAF and shorty headers. I'd suggest swapping to a 4.2 block with single port heads. That IMO has to be the easiest swap out there. No IMRC's to deal with and if you can keep your distributor. The only major thing that would need changing would be the air/fuel mixture.
