Broadcast sheet

I have my broadcast sheet and I'm trying to figure out what the numbers mean engine I believe is 364 trans is 65 and prop shaft is 37 any help would be appreciated
There were lots of numbers on engines in 1964. For example;
*** 273 x 2 w/push botton transmission
*** 273 x 2 w/3-speed on the column
*** 273 x 2 w/4-speed transmission
In 1965;
*** 273 x 2 w/automatic transmission floor mounted
*** 273 x 2 w/automatic transmission floor mounted w/ a/c w/o power brakes
*** 273 x 2 w/ automatic transmission floor mounted w/o a/c w/ power brakes
For each engine, carburation and transmission there were individual codes.
