Great stuff, thanks for sharing.
I would be very careful of the original oil filter. the filtering media is probably junk and can cause a serious problem. I could see why you wouldn't want to mess with it though. It is kinda shocking to see the condition of the inside of the carb. Looks like new. i was not as lucky with the fuel system on my low mile Hemi Challenger, The car had sat for some 25 years and the fuel system was polluted. I saved everything, but the tank and lines were loaded with a crystallized, smelly, brown junk that wouldn't just flush out. The attached pic shows what the inside of my tank looked like(still trying to figure out how to get the pic to show up in the post). Looks like rust, but it wasn't. If you scraped it with your finger, there was virgin metal underneath. The carbs were removed from the motor and drained so they survived unscathed.
Very cool stuff. I have had the fortunate opportunity to view many low mile survivors in my day, but your Camaro is probably one of the best if not THE best.
