to be honest man there literally was nobody else that would touch that engine. everyone wanted to just swap in a replacement. and my option was have another shop replace it. no warranty. or have gm do it with a 3 yr 100k mile warranty. which is why i opted for that.If you were paying out of pocket, there were probably better options than paying a dealership to do the work.
Maybe its not too late.
You paid for the engine, find a reputable shop that can do the swap for you and have it all moved there. I bet you could have your car back in 2-3 days rather than a few more weeks.
Thats crazy either way.
