'83 5.0 crossfire Z28

I just bought the car and it has an aftermarket hood. It looks rad, but there is no veci label. I've had no luck coming up on this info. I thought it was around 7 deg., but someone also said something crazy like 22deg. or something. Does anyone know the correct timing, and adjustment procedure?

Get engine up to operating temp, disconnect single tan wire that is coming out of main computer harness near distributor(do NOT disconnect 4-wire computer connector on distribtor), set timing to 6 degree BTC, reconnect tan wire, clear any error codes.
