Congratulations on seeing this in your own garage. You made a smart, informative purchase. I look forward to hopefully hearing and seeing more about your car. It truly is a rare car in having original drive train, the engine option, and being a higher optioned RS-SS. My car built about the same time as yours has me additionally interested. Here is a list of my dated components and I would be really interested hearing on how they compare to your car. Enjoy & have fun with it. Sorry for hogging your space.

Below is what I have found so far with the exception of some of the cast dats. I will come back and edit this when I find them.
I have been spending some time under the hood latley. I did find the trans hidden VIN but could not get a clear sight on it. I could see the numbers though on the top of the bellhousing not down by the pan. Plus there was 40+ years of oil and dirt I could not make it out along with the block casting #. However, I did get the block casting date down below by the motor mounts G15 8 August 15th 1968. Below is a listing of the rest of what I have found so far:
Carb: Rochester Quadrajet 4MV 7029204 FF (correct for L34) could not find the date code though maybe a hint at where I can find it? I found a lot of little numbers everywhere with the RP prefix so I think those are individual Rochester part numbers.
Intake: Intersetingly had Q-JET cast into the passenger side front and the firing order on the drivers front forward of the carb.
The intake casting number: 3931067 cast date H 5 8 or August 5th 1968 time 11:00
Cylinder heads: both 3931063
passenger side head cast F24 8 June 24th 1968 6:00
drivers side head cast F26 8 June 26th 1968 9:00
RH2 3916178 have not found the cast date yet maybe someone can hint where to look.
Cast number 5468309 Front tab US = 1969 Power disks 1-1/8" bore
Power booster: Delco Moraine mounted upside down at the 7:00 position
tab side 1 9204 = 1969 disks
tab side 2 285 = Julian date = Oct. 11th 1968
Distributor: 1111497 396/325HP hmmm maybe a mixup on the assembly line perhaps? Seems to be because the date code is correct H13 8 August 13th, 1968
Alternator: Seems to be a replacement (If anyone knows what this part number is please let me know.)
cast numbers: 1103175 42A
1F 4 12VNEG
Radiator seem to be a replacement also but I noticed that right away. The 396/350HP non A/C (RPO C60) should have been a 3 core radiator striaght neck. The A/C cars had a 4 core radiator with a curved neck for the upper radiator hose to clear the compressor. However, this car has a four core straight neck radiator. So even though the radiator does not have the tag it is a later model upgrade. It is expceted though as I don't want to overheat the engine running A/C on a three core original radiator. It does have the original 4 blade fan. I think I need to add a 7 blade clutch fan and keep the old 4 blade fan as part of the orginal equipment to this car.
Thanks and that is it for now. I have pics, but my camera is not that good. I will see when I get a chance to download them. Next task on the list is to remove the alt. to get a better photo of the stamp pad, but that is for another day.
