The first two pair are probably dates and/or transmission serial numbers. The third character set looks like a partial VIN...
1 - Chevrolet
3 - 1973
K - Kansas City
434769 - sequence number, Chevelles began with 400001 in 1973 at KC.

According to http://www.novaresource.org/trans.htm, TH350 transmission codes are found...
TH350 (1972 and earlier)= on the upper flange of the transmission housing converter opening
TH350 (1973 and later) = on the right vertical surface of the oil pan
...but you said these are found on the bellhousing flange. Could be the resource above isn't 100% correct. Colvin's also says the TH350 in 1973 had the code on the transmission oil pan flange, passenger side.

Would you have a photo of it by chance or is up in the car where you can't really get to it?

Re: Turbo-350 Codes?

Also look on the accumulator cover on the passenger side of the trans.

Re: Turbo-350 Codes?

I will get a picture once i get home from work this afternoon, however the codes i found are on the torque converter opening flange, although i dont remember which side right off the top of my head.
