[William M.]

What is the latest consensus in NCRS for the water pump used on a early 1961 Corvette with the top tank radiator?
I have my opinion. What's yours?

So far there have been no replies to my post.
Look at the four pictures of the water pumps and give your expert opinion as to which water pump was used on a early 1961 Corvette with the top tank radiator #3147516.
Picture 1) 3736493 water pump(like 1960 Corvettes used)
Picture 2) 3782608 water pump
Picture 3) 3757248 water pump with plug on top
Picture 4) 3782609 water pump with plug on top
Now that you have made your choice, which front engine motor mount was used between the water pump and the engine?
Choice A)Straight on front like a 1960 with no center cutout
Choice B)With center cutout

William
Since the Judging manual says water pump 609 and motor mount has a cutout, it really doesn't matter what any ones else thinks. This is how the car is going to be judged. You've been a member a long time so you don't need me or any one else to tell how to try to get the manual changed if you think it's wrong. Just my old two cents

This is a very interesting question that Bill has posed. My C1 knowledge is so limited that I cannot hazard a guess but I am interested in learning something here. However, where are all the C1 guys? Are they all in Florida? Are they (gulp), "no longer with us"? To date, over 1,000 folks are, apparently, interested in a sighting of Roy Sinor at Barrett-Jackson but no one can offer anything up on this interesting technical issue?

They're all afraid they're going to have the wrong water pump when this story unfolds.

I probably know less than you about C1 but I'll guess the 3782608 and 609 1st appeared about the same time the 327 block did for 1962.

The 3736483 sounds like a number that might have been released for 1957 and used for HD truck??

The 3757248 around 1958??
