How much do you wanna spend?.....
You can spend $3000 on a OBD2 V8 swap.....
Or $4000 + on modifying your OBD2 V6, which will never give you the kick in the butt as a V8, because it is the increased torque that is the fun factor.

Forget the 4.3 upgrades. If you're serious about more performance do like Darren suggested. And a V8 swap doesn't have to cost $3000.00. If you're good at scrounging you could do it for half that.

W in the VIN = Fuel Injection
Z in the VIN = TBI

W is multi-port FI. Z is TBI.
