pretty much all old pushrod V engines with single roller chains have plenty of slack by 100kWhy did they have to do the timing chain so early on? I have never done one on a 3800.

Yeah I have done few too. I think the original had a bearing that would go bad and it would clunk...loudly. I bought a replacement from Rack Doctor on line was a quality unit with all the updates.Good time to replace the steering rack. I replaced lots of those on this series of car back in the day.
I have seen those before but that is like what I had in my 71 K5. The 3800 in the W-body had all metal parts with a small tensioner.I am not sure if these used a nylon tooth covering on the cam gear but that was usually the reason for changing the old ones on quite a few engines when you found the nylon teeth coming out with the oil.

Was about to say the same thing. I still had 160k on an 87 Olds 307, when the water pump failed I did the chain too. It had slop but not enough to jump time anytime soon. I had an 89 Caprice 305 which was after they stopped using nylon gears. It had 332k miles when I scrapped it, original chain with very little slop.I am not sure if these used a nylon tooth covering on the cam gear but that was usually the reason for changing the old ones on quite a few engines when you found the nylon teeth coming out with the oil.
