Re: List 4557 "GG" carb ('70 LS6 M/T)
John,
Did not know that there were part #'s (3967477) w/o the GG. Don't know what the application would be for that. A Chevy BB solid lifter A/T application in 1970 was . <font color="blue">3969894GP </font>

Re: List 4557 "GG" carb ('70 LS6 M/T)
Right here Rick, hoping to pick up info on this mystery myself.
Question: How many plants built L78 and LS6 cars in `70? Wondering of the "GG" suffix code (et.al.) may be assembly plant related?

Re: List 4557 "GG" carb ('70 LS6 M/T)
While we're on the topic (and to avoid starting an unneccesarily similar thread), has anyone seen a non-"GE" 4346, or a non-"DZ" 4053? (concentrating only on production dated carbs for the moment)

Re: List 4557 "GG" carb ('70 LS6 M/T)
For what it's worth my 70 L-78 Camaro has the non "GG" carb. with a Dec 69 date. The motor was assembled in April of 1970.
I was told it was the original carb. but who knows.....

My "GG" info came from Colvins, for what its worth.

Re: List 4557 "GG" carb ('70 LS6 M/T)
I asked the "king", and he said early production carbs[usually 1st 2 months of production did not receive the two letter suffix. He also said no 96X 97X 98X 99x 4557s have the GG suffix[90x was about the cutoff on 4557s to receive the GG code]] ,also that it crossed over to other carbs as well...I asked him about the dec 69 without a GG code and he said hes never seen one that late w no GG stamp...Email him direct if you need any more info..Kid

Re: List 4557 "GG" carb ('70 LS6 M/T)
Perhaps a Corvette carb without the GG? This site says the 4557 would have been used in some '70 and '71 Corvette 454's as well. Colvin's gives a different # altogether for the '70 and '71 Corvette.
