KC did not specify why the top oiler block is subject to cracking at high rpm, which I believe was in the 6000-6500 range. I would certainly welcome more information on the subject. I have no ax to grind either way. FE's are a fascinating subject!
Is it the center oil galley? Were the top oilers cast with a slightly different compound than the side oilers? There doesn't appear to be any difference in webbing of the lower crank area. So, what gives (pun intended)? 
Perhaps it was a referrence to the "2 or 3" irrigation blocks...
