I was recently received a deduction for an incorrect number on the Harrison expansion tank tag. The JG claims it should be 374516. The number on the tag was 3147516 with date code 60F. Car build date August 12, 1960. I ordered a new tag from Dewitt, having given Tom all the relevant information on the car, and it came back with the same number 3147516. Am I missing something?

Let's Just Say That The Blueprint
for this radiator - with a last noted change of 2-2-61 - calls out the part # as 3147516. I would not presume to call a JG "wrong" but in this case, they are a little short of being correct. -

YES!
The 1960 aluminum radiators came in four different versions. The first had a part number ending in 516 (4-11-59) and had a smooth tank surface and no sight plug. The next version sported five reinforcing ribs on the top of the tank (10-26-59). Next a sight plug was added (1-7-60).
On 6-14-60 the top tank got a new part number ending in 116 and an extension to the drain petcock. No production top tank radiator was painted. They were all used in raw aluminum. The service replacements were all painted soft radiator black (asphalt base).
Since you have an August build date, I would consider a 116 correct BUT would NOT rule out a 516. Who accurately knows what inventory control was in place at St. Louis?
Pedantic judges who consider configurations as absolute per judging manual and cast in stone are a menace to the hobby. Common sense should prevail. Also, what ever happened to the credo, "The Owner Gets The Benefit Of The Doubt"?

Re: 1960 270hp Expansion Tank Tag
Have you checked the Noland Adams restoration book. I recall reading something there about the part number being 3147516.Comment

It WAS 516 for a while! *NM*

Re: 1960 270hp Expansion Tank Tag
I'm a little late with this but here's my thoughts on this. I agree judges should be a little flexable on this one. I mean (4) four version in 1 1/3 years is a little much to figure out what happened. I am pretty much using the first (3147516) tag on 60 cars and the second (3151116) for the early 61's. Since this car was during the transission, I went with the first one. I think with all the documentation out there it is safe to say the 61's were all final versions and had the hole and ribs. But just when you think you got it I find something to throw a wrench in the rules. I picked up an original radiator at Carlisle (3147516) dated 59K. This one had the sight hole and was flat (no ribs), which would make a 5th version. All the information, drawings, and documents I have say the ribs came first, then the sight hole.Comment

I would agree with Tom
My information shows the ribs being added 10/26/59 and the sight hole added on 1/7/60. Perhaps what you picked up at Carlisle was one of the original tanks from the 2 Cunningham cars at Sebring - the resident production engineer from St Louis, Phil Passon, was present and was aware that this change had been made - Momo decided he wanted it done to the two cars and Ed Cole and Passon blanketed Sebring hardware stores until they located a "plug" that could bwe used. More likely, you just found a tank that some other owner decided that the modification made sense.Comment

Re: I would agree with Tom
I don't think so. The plug is an original "clover" TY-16 and the tank is stamped with the "fill here" instructions. Something you couldn't add after the tanks were welded together. It's wierd!Comment
