Holley ID
I know this comes up all the time but can anyone interpret these numbers off the Holley on my ’66, 300HP, 4-speed.
3884505-DA
3367
2014
The metering block has 4508 stamped on it and on the top rim of the bowl is what looks like a replaceable date stamp that says 6R2747

The 2014 date code is the 201st day (3rd week of July) of 1974 (or 84).

I have a 65' Vette with a 1970 350cid; it has a Holley with the same numbers as yours except for the date - mine is 2912. I too would like to ID specs and initial car installation. I'll try to follow your thread.

Post the other numbers on the air horn. And I would suggest starting a new thread instead of using this ten year old thread
