Buy an LS motor. No way to turn a Gen 1 into a Gen 3. The only parts that are the same are the rod and main bearings that's it.

So what can i get an LS motor out of? And a tranny and wiring harness.

The easier ones to find are from pickups but car engines are out there. You can phone wreckers in your area to find what is readily available. Trans options include newer types that are behind the engine you what to buy, but you can also use the older th350, th 400 etc. Harnesses can be bought new from people who will build what you need, or you can use the donor harness, and modify as needed, but this will also require getting the computer unlocked, and maybe flashed for engine mods.

Hope this helps get you started

Do some searches in the forums, and you will see most of the answers that you need

car-part.com and search the local wreckers for an engine
I got a 6.0 mostly complete for less than 800$, fairly low miles
