The block has been checked for cracks, I asked what it needed done to make
it useable and all it basically needed was the mains align bore honed,
punched .020-.030, and decked .010 to square it up.
It has the mounting bosses cast in it that are similar to the ones on my
3.9, I'm just curious as to what makes the difference between the Pre-Magnum
and Magnum cylinder casing castings?
I'm going back later this week to check it further and see if I can find the
casting Date on it..........
