Truth to this statement as well. The importance of starting with a surgically clean block can not be overstated. To this day, the amount of casting sand and crud I've cleaned out of blocks is truly surprising.

There is one thing that I am curious about. I am exclusively an "8BA guy" and have been through 7 or 8 engines. Most of them had minimal debris in the water passages.

Am I just lucky, or did Ford get better at cleaning blocks in the later years. Is this a phenomena mainly seen in the earlier engines?
