Reason I’m asking. I started final assembly on my 440. Turned it over on the engine stand to put the oil pan on, heard something loose. Found what appears to be a junk of the cylinder wall in the water port on number 1. :BangHead: Keep in mind, I had this block “professionally” machined and sonic checked… been sitting on my stand waiting for the cam shaft I’ve been saving for. Finally get that and now this.
Luckily I have a spare 440 block.
