428 Cobra Jet Radiator Cooling Fan Shroud Identification

A radiator cooling fan shroud helps concentrate cool air as it's pulled through the radiator by the cooling fan. All 1968 - 1970 428 CJ and SCJ Mustangs were originally equipped with a cooling fan shroud to help keep our monster motors from boiling over. Here's what the shroud looks like:

The original fan shroud used for 1968 - 1969 Cobra Jet Mustangs carries casting number C8ZE-8146-B (serviced as part number C8ZZ-8146-B). The original shroud used for 1970 Cobra Jet Mustangs carries casting number C8ZE-8146-C (serviced as part number C8ZZ-8146-A). The 1975 Master Parts Catalog says that the service part number for all three years is C8ZZ-8146-A, so it looks like the C8ZE-C shroud replaced the C8ZE-B shroud. The -C casting number is shown below (click on the image for a larger picture):

You may have noticed that Ford Motor Company and many parts vendors still offer a Ford service replacement shroud for our Mustangs. You should know, though, that these shrouds are not *exactly* like the shroud that your car was originally equipped with. The difference is in the "FoMoCo" logo that appears on the upper left hand corner of the shroud. Here'a a description of the differences in the FoMoCo logo according to Allen Cross of FoMoCo.com:

"Basically, it appears that the first series uses the "boxed" FoMoCo logo, upper L/H flange. Sometime after commencing '70 production, Ford began switching over to the oval, script logo on all newly-made parts. Where needed, fixtures were modified or replaced to accomodate the change. In all cases of which I'm aware, carryover parts were used to exhaustion, then redesigned ones began to filter in. The old shroud fixture was altered to partially obscure the "box" logo with a series of short strokes, something like this (Editor's note: Allen's original description used a drawing that I've chosen to replace with the picture below.

....as opposed to the final version, lately still sold by Ford, in which a number of full-length strokes almost completely obliterate the logo. (Picture again added by the editor. Click on the image for a larger picture.):

In both, the new oval logo appears at upper left, inboard so as to be on the curved shroud itself rather than on the mounting flange."

Allen recently advised me that "the latest 'repro' (C8ZE8146B) shroud includes a moulded ID number plus 'FoMoCo' logo...in a rectangle, no less".
