First, he advertises the kits for a .060 over bore. Most factory blocks are not safe with longer strokes at .060 over, and there are aspects of the kits that you ned to pay atention to. Such as the ability to use the factory style internal pickup, or oil ring supports, piston compression heights, etc.



Ok, ... RB block - so it will take the longer stroke.
External p/u is not an issue.
Apparently the pin does not interfer with the oil ring supports.
Compression height for the 528 is 1.423

Why are factory blocks not safe with .060 over on a longer stroke?
