I think that is the same block that I have. I never had any issues with my block. We bored it to size and put it together. No leaks, everything bolted on just fine and the rear main is nice and dry after a bunch of dyno pulls. I'm planning to sell my iron block later this year since I don't need it anymore but it has been good to me.
If I remember our conversations from '07/'08 - ish, I think I remember the one you ordered was P5153944? Should find the number stamped in the front.
It's nice when things fall into place.
The issue was on the left side of the block, driver's side. For some reason in the first run or two, on the samples available to us the ditch was always deeper on the left. Resulting problems only happened twice in the whole run that I am aware of, but it was a concern. Most of them were fine. It had to have been 08 or 09 when we fixed it. I might be able to round up a picture of the late style block with all that cutting omitted.
