That's just given me an 'AHAH!' moment... about 30 or more years ago I had our Chev 216 rebuilt by a company in Brunswick I think it was... anyway it was when I was working for Hughes Auto Spares which is where things like the NOS distributor came from. It always had a light knocking in it, even though everything else seemed to be good... the crankshaft and big ends were done so it seems the noise may just be due to the gudgeon pin bushes. We fitted the cast iron pistons as I was able to get them NOS at the time.

had a similar problem, a slight knock cold, lost compression during a long hot pull but the Chev made it home. Discovered bush came loose in piston,worked out into the cyl wall, big groove up wall. All pistons had cracks into gudgeon area, motor had done 25,000 mls, std bore, no shims left on rods but crank 0.005 wear. will rebuild after sleeving.

I did a bunch more blasting and painted these parts. I found a hood setup after a lot of looking. It came from Ontario. I'm going to try to finish the sandblasting before it gets too cold out. I like to do that job in the fall since I can wear a Ski-Doo suit for protection and not have a melt down.
For those who keep asking how much paint you need for a truck, these parts took a gallon for one coat. With stuff like the seats you waste way more than you use, but the shop floor gets a fresh look.

Dave,

good to see you have continued on the C8 again! Am I correct in assuming your C8 has the cowl vents? Could you post a close up of the tube and valve which sits behind the vents?
