2000 v6 to LS1
The real best way is to sell that car for whatever you can get for it and buy a Z28 since a Z28 automatic of the same year as yours can be had for 8 or 9 grand. Figure your car is worth about $4000-4500 now, plus around 4-5000 in parts to do the conversion, plus a ton of your labor and time, plus when you're done you'll havea frankenstein of a car that won't be worth as much as a real Z. The only benefit to the swap is cheap insurance. Which can be a double edged blade since if you wreck it or if someone steals it you get V6 values applied to your claim.
But if you're stuck on converting it look for a whole car. I can probably source one for you for in your area if you would like.
