Quadrajet question

[Innuendo]

Best I can remember is that BS didn't happen until WB and Commodore. HZ didn't have it.
If you can show me pictures on the stamped numbers on the drivers side of the carby I can decode for you.

Thanks Night rider. My Carby was off a WB 253 that I've had rebuilt to suit my 308. The one in the picture was just one I found online.

Cool. Thanks again Len. My carby has plenty of spare vacuum ports I can use.
