Is the BB and SB diverter valve the same in 67 corvette?
Opinion on what a very nice original BB early take-off system is worth?

Thanks, Terr

If your talking about K19 smog system I can’t answer the diverter valve is the same but I have seen people ASK upwards of 5k for a complete system. What people pay is anther story

The OEM mixture control valves (AKA 'diverter valve or 'carburetor air bleed valve) for small block '67 is 7033546; for big block '67 is 7033547. They eyeball and are dimensionally identical, except for the small stamped and cast part number derivatives located at two places on the part. Photos below are NOS/NIB 7033546.

Thanks for the reply. I don't know 67 stuff very well. Trying to learn about the 67 stuff. Terr

So I have done some looking. What I see is that the same casting was used for both parts and the casting numbers 7033533 are found in the little circle of the part.. As the part is manufactured, it gets another part number stamped into it. That number will be either a 7033546 or a 7033547, etc etc depending on application.
