Holley date code question

[MQ]

Hi all,
Always reading, rarely posting, but I've started to make a detailed inventory of all the more special Camaro crap I have laying around and have gotten to my Holley carbs.   I have 2 that I want to make sure I have figured out correctly.    Any help would be appreciated.

#1 - 3959164, list 4348, BD1.    This date code makes no sense to me.    It is pretty clearly stamped, but I'll check it again when I get back over to the shop.    I am pretty serious when I write numbers down.     By the number it codes as a '69 L-78, L-89, L-72 carb.   Oh yea - vented primary bowl, manifold coil style choke.

#2 - 3923289 DZ, list 4053, 0523.     This should be a service carb made in February 1973 for '68 L-78, 68 L-72 and '68 & '69 DZ service.   Non vented bowl, manifold coil style choke.   Am I correct here ?      This is the carb off my '68 L-78 car.    Bummed it a service replacement, but I've owned the car since '81 so it's been there forever.

Thanks,
Dave

Cheverolet By The Numbers:

1. Do you mean 4346?  That is what is listed for the applications you list...  801 would be a better date.  I know you said you typed correctly...

2. That is what the book says.  My center carb  on my 3X2s is a service replacement, too.  Oh well...

My notes do say 4348 and I looked at that date several times as I knew it was odd.    But, old eyes and maybe not the greatest light.     I'll go over and check again and even take a pic that I can blow up Helen Keller size to really make sure.   

Amazing what you find when you go digging into piles of stuff that you haven't looked at in years.    I found a pair of 660 center squirters that I have no idea where they came from.    Tach & gauge clusters I forgot I had.   I'd just pick up stuff as I found it and just stash it away.   Pleasent surprise to find dash clusters for both 67s & 68s with all 3 redlines.    Puts a smile on my face.

You know, with the right sauce crow really isn't that bad...    Direct sunlight really helps !    Correct info.

I didn't follow my #1 rule.    If it doesn't look right, figure out why.    ugh.
