Seems like non of you above have ever taken a close look at a bigblock engine casting.
That's "normal".
I personally would have smoothed the edges during the build, but that's how most of the later blocks came from the factory.
Sorry, but when I saw the chip on the right side of casting and the discoloration in the casting it that area, it bothered me. I too have wrenched on these since the 80s and I never saw one that ugly. I know I would feel really guilty putting an engine out for sale looking like that. A little work with a carbide bit would have helped a bunch, not only for the oil flow, but for chamfering the rough edges of the casting. I never said it wasn't of use, I just would not be comfortable using it with power adders or ultra high performance in my opinion. I really don't feel the insults were needed
