    Thanks to the recent and interesting posts on this thread, maybe it should be moved to our "RESEARCH" forum...

    Definitely needs to be moved. But, how is that done?

    What do you guys think this engine is?

    I'd say it was a 260 and that somebody just put a four-barrel intake on it. BUT...the seller claims that the block and intake have the same date code (3C1, March 1, 1963). Could this be a 260 XHP!? I've communicated with the seller over the past several days, and communication is poor to say the very least. Anybody in that area of Ohio that could go inspect it?

    The heads are marked XE-10021 and XE-10021-3 with 1.67 / 1.45 valves. I have not seen them myself but a member of our group has.

    Could you ask him if he took note of the number on the end of the head? Known Hipo numbers are 19, 20 and 21. I'd be very interested to know what this number was for the XHP.

    Thanks for that info, rr64.


    As you probably know, the C2OE-6015-J block has the six inch motor mounts. Whether the C2OE-6015-J was used or the C3OE-6015-B (with 7 inch mounts) was used for the XHP 260 has been a point of some contention. It never made sense to me that it would have been only the C3OE-6015-B block, but there could have been a running change with both blocks being provided from Ford to Shelby at different times.


    Did you note whether the SK12569 intake also has a regular Ford casting number, like the XE-106391 intake does?


    An acquantance of mine that is a Boss 429 guy says he has a descriptive listing of "all SK numbers", but I'm not sure if he means only the Boss 429 SK numbers or really ALL SK numbers. I need to give him a call to check out an SK number for me on a Holman Moody 429 cam. When I do, I'll ask him about that.

    I'd like to change my previous comments about the NOS ones that I had. Now that I think about it, I can't remember for certain whether they looked chrome or not.<img src=images/icon_smile_blush.gif border=0 align=middle>

    The C2OE- and XE- engine part prefixes were found in very early (early to be completed) cars with 260 engines. I have heard rumors of an SK- marked 1-4V iron intake but I have not seen one. As <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana" size=2 id=quote>


    I am familiar with the iron XE single four-barrel intake used on the 260 XHP (1962-early 1963). They have a casting number of C2OE-9425-K with an additional casting number XE-106391. I have not seen or heard of an SK marked intake for the 260 application, though.

    If the information that Shelby and/or Ford supplied to the NHRA is accurate, a 1963 Cobra head can be distinquished from a "standard" 1963 Hipo head. The valves are larger in Cobra applications.


    In 1963:


    289 Hipo head - 1.677 intake/1.457 exhaust.

    289 Hipo head used in Cobra - 1.875 intake/1.625 exhaust.


    [The 260 XHP head used in the Cobra in very early 1963 - 1.843 intake/1.625 exhaust.]

    I had a pair of NOS Hipo backing plates (and may still have them packed up somewhere, but I think I sold them a few years ago). They had the part number and the Fox Co. on them. That's not to say that they all did, but this pair did. [Charles, they sure looked like chrome to me, as does the pair of '63 Hipo backing plates that I have. If they are anodized, I can't tell the difference.]

    Nice post. Thanks alot for the information. So, really no way to know exactly but at least the numbers to match accordingly to the 1963 289 COBRA heads, they are exact.


    These may have to stay with me for a while. They do not appear to be messed with.
