date codes for distributor on 68 396

[RAS68]

My question is about relative stamp dates between correct distributor and the car and engine build date and the other engine parts. I have read many of the posts on the forum but I haven't found good answer to my question. My car is 1968 L34 with A/C PS,PB,PW. The cowl tag indicates build date is 3rd week of July 1968, (Nor plant). The block has been decked at some point and numbers are gone. The Block cast date is February 1968 ( so I doubt it is even original). But I have been trying to get all the parts to be correct just for the fun of it. The heads are correct and have cast date of F 68 and intake is correct with cast date of E68. The exhaust manifolds have correct codes and the dates are D 68 and E 68 ( but hard to read). I found a correct # and date carb from a member on this forum ( I am so grateful). The distributor is a rebuilt and is an incorrect number stamp. It runs fine but I want the "correct" #s. If I want to find an original distributor should I look for a date to match the heads around early June (F) or earlier than that with maybe an E or even D date?
Thanks,
Allen

I have an extra 1111169 8E22, I purchased this awhile back. Then when I started to go through my stuff. I found my original  for my L35 M40. If your intake was dated E68, most likely the distributor what be very close, in my opinion

Thanks for the reply 68bb02. Your rationale for E sounds reasonable to me. How much do you want for your extra distributor? Send me a PM and I will get back to you. I still would like to hear from others about the dates and date gaps between engine parts.

Don't be so sure about your engine being not original... were the manifolds and heads etc with the car or did you collect them?
Was the block with the car or not?
Reason I ask is July 3rd week is near the end of production and the assembly plant would be Depleting stocks for the model year changeover - (the pilot 69 Z28 N500003 was built on a 68 floor pan in July of 1968), restocking of engines did not dictate a first in first out inventory system,-  a February built engine or March built engine would not necessarily be out of line for an end of year built car.
