03 silverado 4.3 to 5.3 or 6.0 Well I recently sold my 82 cutlass cuz it was a money pit. So I sold the rolling chassis for 3grand and bought a 03 short bed v6 and I want to convert it to a lsx. I still have my lq4 an rebuilt my 4l60e with goodies. But I I know I will need an 03 v8 harness and make it dbw. But I don't know if I will just need the harness in the engine bay or both engine and under dash. Has any one ever did a swap like this?
