"I dare to summarize that the "stronger STOCK blocks" of folklore are not better-enough in the Main Web to be siginficant."

"My only valuable opinion on this is the 67-400 showed a bit more in #2 #3 #4, while even my YK 428 4-bolt blocks (Nov 1966, Dec 68) did not show a real value in #2 #3 #4."

Last time I looked Mains 2,3,4 were the ones that the factory put 4-bolt mains on AND if you had a non drilled 67 block with the extra "bit more" the block lends itself very well to splayed caps on the 2,3,4 mains.

If you run a front and rear motor plate, the sides of the block only see the stress from the splayed caps. 3 years of high hp over 1500 can't be all wrong.

ps I will tell you another secret. Marty paid to have a company stress relieve the block with one of the special tables for that deal. I firmly believe that helped.
