Happy new year all. would anyone be able to help with a flywheel date code 6A19 Please.

Thanks mike kiwikcode.

Are you looking for a 6A19 flywheel or wanting to know what it decodes to? (Jan 19, 1966)

kiwikcode_old · January 5, 2010 at 2:30 PM

Thanks charles I'm looking for a jan of 1966 flywheel if you can help

Cheers mike.

I've got the original flywheel off my Jan 66 kar but I'm not sure you would want it. It's been surfaced as far as you can go and has lots of heat cracks...

kiwikcode_old · January 6, 2010 at 2:24 AM

Thanks for the offer I would like to get one better than that.

Cheers mike.<img src=images/icon_smile.gif border=0 align=middle>

What casting is your January 66 flywheel -- C3OE or C6ZE? I would like to get a closeup picture of any stampings just outboard from the counterweight, or other identifying marks.

Not sure... I'll take a look and grab a couple pics today.

It is a C3OE. Took a couple pictures but left the camera at work. Will try to remember to bring it home tonight...

Chuck, I have a question in regards to your flywheel, I tried your e-mail with no luck, everyone else's worked but yours wouldn't. Contact me at ltatro@verizon.net, Thanks, Terry

Terry,

Not trying to put my nose into where it doesn't belong. If you're looking for photos of a '67 HiPo flywheel, here's a thread where I posted photos of my '67 flywheel. Scroll down toward the bottom.

Tom, that's exactly why I was trying to get ahold of Chuck. I have a flywheel that's exactly (almost) like yours, in fact I think it's the same casting date. My question to Chuck refers to the engineering number C7ZE-B. Your flywheel's number is C7ZE-A. My flywheel also has the C7ZE-B engineering number, it also has the same paint daub & number 2 (as yours), and brinnel test mark. I've chatted with other forum members who revealed that the B stamp denotes a standard flywheel as opposed to the A "hipo" stamping. Just curious if Chuck knows any history on his flywheel that would validate it coming from a hipo assembly. Thanks, Terry

bobmannel · January 15, 2010 at 10:40 PM

To Chuck and all. Yes, I would very much like to get pictures of flywheel markings -- whole flywheel, the close up of casting number/date code, and marking along the perimeter -- in high resolution JPEGs. (My email is bobmannel@charter.net.) For HiPos, there are two castings -- C3OE-6380-B and C6ZE-6380-A. The former will also have a circled C outboard from the counterweight. The latter will have a C7ZE-A stamped into the perimeter. The standard 289 used the same casting -- the earlier one will have no circled letter stamping, the latter one will be stamped C7ZE-B. And, if you find a C3OE-6380-B casting with a circled A, it was used for the 1964 260. Some of this is verified, but I am working on getting a bigger data sampling. It is all about how the flywheels were imbalanced. The 260 was 26.2, 289 was 28.2, and the 289 HiPo was 30.4 ounce-inches.

I am working on a CD version of my book "Mustang & Ford Small Blook V8, 1962-1969". It will incorporate all the corrections and include supplemental information. I did not cover flywheels in the book, but will do so in the CD version. Can't give you a time of availability yet. These things take time.

Here's a pic of the original flywheel from my Jan 66 kar. Bob, I've emailed you a couple pics.

So, as I understand it, your C6ZE-6380-A, 6J21, C7ZE-B flywheel has a Brinell marking. The C7ZE-B identifies it as a standard 289.

In investigating 63-64 flywheels, I have not yet found any consistency in hardness testing. I have found a few flywheels with what looked like a possible Rockwell hardness test with a cone impression, but it could be a casting flaw. At any rate, I found the same mark on both a HiPo and 260 flywheel (both C3OE-6380-B castings), so it is not germane to the 289 HiPo distinction.

The C3OE-6375-C print calls for identication by painted part number or equivalent marking in the area at the The only difference is in the imbalance. The C6ZE-6375-A print calls for a steel stamp prefix and suffix of the flywheel assembly number in .18" size letters to a .02" max depth in the area of the outer perimeter. Neither print mentions instructions for performing any hardness testing on the casting of the flywheel. Both do mention the cast iron is to have a Brinell hardness between 179 and 235.

Please keep collecting information. So far, it seems that the C6ZE-6380-A castings for HiPos will be stamped C6ZE-A or C7ZE-A. The Brinell hardness test might be incidental. Info I received from someone who talked to persons in the engine plant at the time indicated that the casting material for flywheels was the same for 289 HiPos and standard 289s. The print agrees.

For the C3OE-6380-B casting, it would appear the primary identifier was the color of the paint. If so, need to determine the color for standard 289 flywheels. I have confirmed circled C markings on 63 HiPo flywheels, and circle A on 64 260 flywheels. But, on standard 289 in 64 and 65, I have not found circled letters nor hardness markings. Need lots more additional information on any C3OE-6380-B casting for 63-66 production 289s. Specifically, I have yet to see a standard 63 389 flywheel (only found on 63 Galaxies late in the year); or a 64 289 HiPo flywheel. Need more data on 65 289 and HiPo flywheels as well.

Hi All thanks for all the reply's I have just got back from how

christams Holidays and I see there is no reply's offering to help me

I just bought a C30E- B date coded 6A13 off of ebay . I'm waiting for it to be delivered. if I can't use it I'll be sure to let you know. But it looks like it's not a 30.4 0z so I don't know if you would want it. Would you want it if you had to re blalance it?
