Hello, I tried looking for an answer through multiple posts so I apologize if I missed something somewhere.

I’ve bought a 5.7 vortec to swap into my 97 4x4 5.0 vortec
I have a few questions

1. This new engine is from a 2wd, will I run into any issues putting this into my truck?

2. I bought the ecu and harness from the parts truck aswell, the parts truck was a 2wd will this ecu work correctly with my 4x4? Setup or is it still just plug and play

3. Can I use my current 5.0 harness and computer if there is any difference with 2wd ecu and 4x4 ecu


Any info will help thanks
