Hi All. I am looking for input from some experienced & knowledgeable builders of performance Gen3's:

1. List of different engine block castings used since 2003;
2. Differences between same block castings internally & externally;
3. Most commonly used Gen3 in performance (i.e. VVT or Non-VVT)
4. Principle common areas of failure

Hoping for some additional insights.
Thanks in advance.

Darren
