I'd say it's from a smallblock mid 70's corvette w/those brackets.
That doesn't look like a deepgroove pulley either.
Can you read a part# behind the diverter valve as well as the part# & date on the SMOG pump?

Re: ID needed
 

Ill go look....
On the date code, where is that exactly.
Ive never seem to find them every time...

Re: ID needed
 

Look on the bottom of the SMOG pump,for a machined aluminum boss that should show something like 21892S.

Since I never owned a small block vette, are they short or long water pumps in the MAKO SHARK bodies?

Re: ID needed
 

Corvettes were all short water pumps.

Re: ID needed
 

So, what smog set-up do I have here???

Re: ID needed
 

It looks like 68 Chevy small block smog to me. The bolts that hold the rear cast piece of the pump to the center aluminum section have WB head markings. Those are 1968. The Diverter valve extension doesn't look right. What's the part number on the pump. Also, look at the diverter valve. There is a flat spot where it bolts to the extension. That's where the part number is stamped, five numbers long.

I have 67 and 68 SB bracket sets that are correct if you want to compare. Both are a little different. Send me a PM, if you're close by maybe you can stop by and I can look it over for you. Martin

Re: ID needed
 

How do I read the date code here for a smog pump?
I will give a complete uneducated guess:
1-25-9 1(?) S(Saginaw)
Once again, I have never attempted to decipher these stampings before, so this is a complete guess!!!

I didn't see a pulley number. Is it 3927116? If so, is it stamped in a straight line next to one of the mounting holes or is is in a slight arc closer to the edge of the pulley.

The pump is dated 1969.

See the diverter valve images at the end of Kurt's article for the stamping location. The number that you had was a casting number for part of the assembly.
