List 4557 "GG" carb ('70 LS6 M/T)

[70-SS/RS-L78]

I thought all 70 SS/L78's had a GG carb...

The August date of my carb is too early for my L-78 with an April build date. I will be looking for a better dated carb. for my restoration.

My L78 is a June build with a Sept dated GG carb.
They are getting expensive...

My Oct.69 built L-78 Chevelle has a Sept. dated 4492,without a two letter GR suffix.I believe there was some production confusion on the deletion of the suffix on the early assembled carbs.,be it over the counter or assembly line installed.
You should use the vehicles Cowl tag date for a Carb. reference point,and not precede it.
I've yet to see any 1970 L-78 Chevelle with a suffix on it's carb,regardless of plant,because they were only produced in the first 100 days of production.
The 6 assembly plants building the LS-6 Chevelle have shown suffixes appearing on their Carbs. as early as Dec.69,probably because the LS-6 was produced later.

I'm more confused now.


In Musclecarkid's post he said that "no 96X 97X 98X 99x 4557s have the GG suffix[90x was about the cutoff on 4557s to receive the GG code]]"

and Eric explained the date decodeing as 98x is August, 99x is September: then no September of 69 4557 carbs should have the GG which mark says his 4557 carb has.

Did I misunderstand what is being said?

Sorry if this is hijacking the thread.

Anyone???

If it is just me being thick headed let me know. I'm fine with that too.

Ever notice when Google'ing Chevy details you often come across old threads from here? . Anyway while searching another topic I found this old thread...check it out. .

If you can find the guy 'youngtto' in the thread it sounds like he may have/had a stash? . Says early but maybe worth a whirl? .
