Isn't the date schema for Holley carbs year(last digit of year,single number), month(single or two numbers, or letter)and then week(single number)?. If so, the OP's 9A1 is the first week of January, 1969? LT-1's, either Corvette or Camaro, were delayed, mid model year 1970 starts so a January 1969 carb date baffles me. My early April built engine has a third week of February (023) 3972121, so about 6 weeks or so.
