Dan, I'm sure you know this. I read years ago that all the blocks back in the 60's (specifically, and maybe earlier and/or later), were in fact seasoned blocks. Left out in a field and "seasoned" with the cold and hot of the seasons. I never heard much more about blocks being seasoned as we moved closer to the 5.0 era and beyond. That may have been why the small blocks specifically was so strong and bulletproof!!
