GM engine information websites?

Does anyone know a site that you can get specific and reliable engine specs?

We used to rely on Henry, but he did that as a favor only:hug:

Henry still checks in once in a while, Simon.

What specs do you need? I could send a text to my wife's nephew at GM testing in Milford.
