Help decode this carb ID

[docgab]

I just picked up another Q-jet from a buddy. I was gonna do a rebuild and decided to decode the carb and see what I got. I feel stupid now. It doesn't make sense to me! Take a look at this and see what you get puleeeese? I am no brain giant, but I've had no trouble in the past, I'm hoping this is just one big brain fart! lol

carb id:

This is my favorite question on this site, because I actually know how to answer you...

I'm going to guess that your "54" in the number should be an 84, since there was not a year where 54 was used. Anyway, your carb was manufactured after 1976, more specifically, in 1984.

I'm also going to assume that the first nine should be a 2 (for 48 state legal) as I can't find any other reference to it...

The 2 means it is from a Chevy originally.

The second 9 means it had a manual transmission.

First off, thanks for your response! An 84 in place of the 54 would make sense, but it is a 54, I've checked many times now thinking I have written it down incorrectly. First part that threw me off. lol

I'm also going to assume that the first nine should be a 2 (for 48 state legal) as I can't find any other reference to it...

Second part that threw me off, the only thing I have found on it is from dyeager's page I think here
that states a 9 means "special" Anyone know what special might mean?

The 2 means it is from a Chevy originally.

The second 9 means it had a manual transmission.

Yup, that was the only part that made sense to me. :-) I do appreciate your help.

I looked that number up too, couldn't really make sense of it myself.

I wonder if special is something like a boat application or a service replacement, although I wouldn't think the service replacements would even be stamped.

There have been carbs like this before that the numbers "defy definition" but I'm sure somewhere in GM's schemes it makes sense.

Hey, thanks for dropping in! All I gotta say is whew to not being able to ID it. I thought I was even more stupid than I really am. I guess I can just tear it down and clean it up for the practice. lol
