It is possible to date the assembly of an engine based on the distributor, starter and generator, if Delco equipped - assuming neither has been changed over the years.
The first seven numbers translate to the part number.
The next five digits date the unit. The first number (always a number) is the year. In this example, '0' = 1950, so 1 would equal 1951, etc. The next digit is always a letter and translates to the month. So, the letter 'G' would equal July. Incidentally, the letter 'I" was not used.
The last two digits, always numbers, translates to the day of the month. Your distributor was built on July 27, 1950. The engine would therefore have been assembled at some point soon after that since KF didn't keep much back stock of items like this.
This same process can be used on Delco starters as well.
And, Harrison radiators installed in 1951-55 full size Kaisers used a similar dating convention.
LOF glass has a date code as well, but that's another story...
