Holley 4053 3923289 carb question
Hi, I have a Holley carb that is stamped as follows:
3923289
LIST-4053
0559
My research so far tells me that it was made on the 55th day in either 1979 or 1989. However, I haven't seen any other examples of the 3923289 stamp without a "DZ" after it. Has anyone else ever seen that? Any input on what I have would be helpful. Thanks.
