That carb number does not exist. Original or aftermarket. I have seen several Quadrajets where the 8 was "lightly" stamped and appeared as a 3.
17058278 specs were .072" Primary Jets, 45K Primary Metering Rods, "K" Secondary Hanger and DB Secondary Metering Rods.

Yes Ethan , I think your right again . On closer inspection (with magnifying glass) it does look like a mis-stamped "8" , that looks like a "3" .
Thanks again .

Not a problem. You have to remember, from the factory, they used a gang stamper. They put more pressure on one side of the stamper, might cause it to look like a different number. I have seen several cases of this. Also, the angle they had to stamp the numbers, was not as easy either. 8)

Ethan , where do you get all the specification details from ?
Is it a book I could buy ?
