Topic: original '67 289 radiator identification

[Bob Gaines]

The extra cooling on a Shelby consists of the radiator as Kurt noted, the shroud (rectangular and oval FoMoCo logo, depending on date) and a slightly larger diameter 4 bladed fan.

I'm also seeing a plate just below the radiator water inlet with a round hole. I thought this was indicative of an original core, but I'm unsure. Can anyone verify or disprove?

You forgot to mention the fan spacer which was a different length on a extra cooling radiator car.

I did and it's only 5 feet from me!
Hopefully mine is stock. It has a number 2 above the Dorman wings and has a circled Ford logo on the nose (or pilot).

C4AE -8546-F is the correct one used on the 67 GT350 without AC ,however there are no engineering numbers to identify it and more then one MFG too. 2.74 is the correct measurement . Most owners make the mistake of using the 2.36 one typically used on the hipo. The correct one is visibly longer and easy to tell when looking at a car. I forgot to say a made up a few to have on the shelf.

That part number jives with my Vehicle Order sheet for its DSO (84-2571).

It's odd that the MPC says "including pilot", since that's not a very good measurement.
One would think the dimension would be machined face to machined face, but including the pilot works well at the parts counter.

I have the 2.74 version including pilot with about .04 being the Ford script!

The important measurement is machine face to machine face because that indexes the the position of the fan blade but I don't make the rules.

... The main difference in standard vs extra cooling radiator was in the fins per inch specification and otherwise look the same.

Can anyone comment, for 1967, the difference in fin-count-per-inch between Standard and Extra Cooling W MO radiators?

My comment is that I believe the default replacement cores available are of the higher fin count per inch .
