Need Help Decoding my Carb...

I've looked around on several sites to decode my carburator, but some stuff dont add up.
Can somebody help?

Here's the #: 7042940

That number is followed by: ME 0972

Thanks for the Help.

 

1972 8 455 A/T California Rochester Q-JET 7042940 2549

 

What source did you use Jiim?
I looked at buickperformance and a couple of other sites and couldnt make a match.

Thanks!

 

Smartin's site:

So it is from a Cal car, which figures since you are there, and it is a non stage 1 455 800 cfm Q jet.

 

ME is the plant code
