1969 SB Water Pump Question

[Steve M.]

I have a 1969 350/350 with a 3782608 water pump. From some previous discussion post there should be a 'S' on the rear of the casting for a correct pump. I did not find an 'S' or a 'T' on the casting. The impeller does have 3923250 GM SM H9 cast into the back. I would appreciate any information that anyone could provide.
Thanks in advance,
Steve

Not all Saginaw-cast '608' waterpumps have the "S". However, as long as there are no reinforcing "ribs" on the driver side of the pump, it's a Saginaw-cast pump.

The 'T' emboss is typically found on the front side of the pump's case in/around the viscinity where the casting number 'lives'....
