If you are using a crank trigger, the Opti has nothing to do with your ignition timing. Only injector timing. Usually when they do that on a pass, the blade on the rotor was hit and knocked to one side. You would have seen that when you had the cap off.
An MSD rotor won't do that. There is a fix to prevent a factory rotor from doing that.
So, you have even had the timing cover and c sprocket off?
Guess your crank trigger stuff was still tight?
Your dampener is keyed to the crank? The LT1s are not from the factory. They can slip on the crank. That would do it.
If you haven't already, I would check my cranking compression.
