Question on k-code replacement block

[snakebite8]

Hey everyone. I am away from home for work so I can't look up if a there is anyway to tell if a factory replacement 289 k-code is differently stamped than any other replacement 289 in 1967. Reason asking is I am talking to some one who says he has a 289 k-code block that was in a k-code mustang but was a replacement engine due to the fact the orginal went. Block is bare. Not having my 289 k- code book with me is leaving me in doubt that this a k-code engine. Anyone here can help me with this. Hate to lose the engine if its realy is one because I am restoring a 67 k-code right now.

There should be a casting date on the block consisting of a numeral for the year (7 = 1967) a letter for the month (A-M with no I) and a one or two digit number for the day (1-31). A 289 HiPo block was the same as any other 289 block except for the main caps.

That is what I thought. I was hopingaybe a replacement block might be a little different. Pipe dream.

Except for the main caps. And I'm sure that some folks out there will change these without the correct matching machining. buyer beware. You recall, every time a 289 gets a aluminum aftermarket intake, all of the sudden it becomes a "hipo"

Factory installed K code blocks were identical in every way to ordinary c code 2V blocks, except that they had "thick" main caps and were specially selected for higher quality prior to machining. The only way to recognize a bare K is by the VIN stanped on the right-front corner.

Exactly, if it is from another Kar, look for the VIN number. A 67 will most definitely be VIN stamped, my December 1964 built 65 k code was stamped. Also look at the casting dates. In the end, I suppose you could stamp a correct date coded block and put the wide Hipo main caps on a C code block and never know it.

The 289 blocks were hardness tested as they were taken from the sand mold, and those testing sufficiently hard got an orange swatch of paint on the rear of the block inside the bell housing area. If the block has been vatted more than once, there may be no sign of the orange paint; however, if only once, you should be able to find traces of the paint still there. Just sayin' The stamped number test won't hold for replacement "K" blocks and not for all original "K" blocks.
Best,
Al

Ok. I never heard of ford replacement blocks for k-codes being any different than a regular 289 but I had to ask.

If you put a set of repro thick caps on a 2V block you'd have a 289HP block.
