I just posted the data from mortec, some were 2 and some were 4. Why they did that is beyond me.......

I never understood that one either. The first time I pulled a pan off one marked High per pass, and seen a 2 bolt, I was dumbfounded. One would think High performance would at least include a 4 bolt.

BTW... what would it cost to have a set of splayed steel caps installed on a 2 bolt block.
I do believe that the high per pass blocks do at least have the high nickle content.
