Re: Doing LS Swap - I have no idea what I'm doing!

Alright, cylinders are dished, so that, along with the crank, verifies the motor size - 5.3 motor. Ran the TAC module number and it comes up as a '03-'05 part number. Programmer was a little concerned due to some discrepancies of PCM and TAC modules not working together.

Anyway, got that stuff worked out and he's ordered the harness and will get the PCM flashed and ready to go. It's now a waiting game for the harness to come in! Due to supply issues, it could be a couple of days - or, it could be weeks... who knows.
