Question on 326 Pump - Blueprint

[Rick A.]

Had this blueprint sent to me in an email and wondering how we can state 1963/4 Corvettes should be using "326" pump, when this ORIGINAL DRAWING for the "326" is dated 5-18-65, as indicated in the "cropped" first picture

I've seen the blueprint previously. What you are saying is what I've been saying for years

Rick -

Pics show up fine for me. We've run this one into the ground for years, but nobody in charge of the '63-'64 JG wants to accept the fact that the 326 pump didn't exist until 1965; they've carried that myth forward AGAIN, into the new 6th Edition.

John,

Thank you! Guess I have had my head in the sand and missed all the previous discussions. So, when I received the email, I just had to post and see what people had to say. Guess everyone believes the myth and we continue to have the wrong water pumps attributed to the 1963/4's!

I'll bite guys, if the 326 is the wrong pump and everyone knows that, what is the correct pump?

Re: Question on 326 Pump - Blueprint

Not to bust anybody's bubble but this (from what I can see, bad photo) looks to be a machining drawing not a casting drawing. A casting drawing would have more dimensions describing the casting walls, draft, casting wall thickness and outline.

Back in the day the practice was to have a raw casting drawing and another drawing taking that casting and defining the machining dimensions.

This could also just be an inspection drawing.

Again into the book of fables and fairy tales?

John, When did the dating of water pumps start for Corvettes ? The reason I am asking is the 326 pump I have on my SHP engine is not dated, Was the 326 pump used on other GM lines before they went onto corvettes in 65 ? It would seem by that time line corvette pumps would be dated.The drawing is dated 65.
Was it possible to see a 326 not dated in 65. I hope you see what I am trying to explain. Thanks Ed

Re: Question on 326 Pump - Blueprint

A lot of people use the 609 pump for 63/4. I understand the drawing and the date of the drawing but I do believe there are some original examples out there with 326 pumps. One other thing to add to the discussion, the guys who rebuild a bunch of these pumps have an opinion similar to what the judging guide states. Do we have any surveys of original cars and the pump casting numbers??
