thanks

Looking at my 351W block, I can't see where they could put the extra bolts and not make the main webs weaker instead of stronger ?
As for the older blocks being stronger, I've heard the same thing over the years, but i'm beginning to question it. I'd love for somebody to do a nickle content test and weight test, and put that to rest one way or another. It could be true or it could be one of those "truths" that have been passed around from person to person so many times and for so long that it just becomes accepted as fact when it never was ?
