I am going though my blocks, picking out a nice one for the new aluminum heads. Ran across An ECZ -a block with 292 journals. Seeing how the block castings can either be 312 or 292 . It is my belief, that the main area is stronger on the 292's . Less prone to cracking.

WHen I send out my 312 crank out for offset grinding, just get mains cut too. Anything I am missing ??
