5.3 LM7 - Fire Up and PCM Troubleshooting

I filmed this in 2017 while I was working on a 2000 GM LM7 engine (LSX) for a swap into a '74 Chevy K10. I modified the stock wiring harness and used HP Tuners to remove VATS from the stock PCM. It took some troubleshooting to figure out why the engine would not run after my first attempt at removing VATS. It was good to finally hear it run!
