As an outsider looking in and having many friends in the US. It is a darned shame to see the collapse as it were of such a great nation.
We can only hope that the powers to be and those who are directly responsible for the problems are smart enough to ask why it happened and how it can be prevented from happening again. In my opinion if those simple questions are not addressed and people are not prepared to answer the hard questions, then we would seriously wonder if the US will ever recover. It may be more than Big Blocks that go, hasn't Pontiac got the chop as well?
Read this book: "The Rise and Fall of the Roman Empire." It's all right there.
Big blocks are really cool but they belong in old Chevys not modern vehicles. They should have been gone years ago. This is one of many reasons why GM is where it's at. I worked for this company for many years and many, not all, of the management still believe the old statement made during the government hearings of the 1950s: "what's good for General Motors is good for this country" That mentality was pervasive for years.
Chevrolet made millions of big block engines. There will be plenty to go around for us old car nuts for many years to come. We just don't need them in modern vehicles. Look at it this way; they will become even more collectible now that you can't get them.
