Title: What does the stamping BZA mean on my Q-Jet?
Post by: 1979SE on February 27, 2015, 08:55:31 AM

I've pretty much decoded my Q-Jet casting number and date code, but what is BZA?  I've read that it could be a plant identifier or an application identifier?  Either way... which plant is it, or which application is it?

Thanks much!

 I believe it is a code that tells you whether it came with your car originally. I have also heard too, that it indicates which plant as well. The code would be on your build sheet, if it came with your engine/car.

That build sheet idea is interesting, I'll have to work that angle.  I do not know if this Q-Jet is original to my car - I do know the Q-Jet was rebuilt before it ever came my way. 

(On my build sheet, GM was kind enough to list tire information in the "Carb" block.  Silly Firestone carburetor.)
