My old Offy catalog refers to later, 12 bolt intake manifold 351W engines as 351K engines. Does anyone know where this term comes from, and if the "K" has any significance?
I did search a bit on the Interweb but did not find the answer.
No such thing as a 351K .. Where do people come up with this crap? (sigh)
For many years, some auto parts stores and tranny shops referred to the C4 (introduced in 1964) as the C5 which caused all sorts of confusion, parts guys vs. customers.
There was a C5, but was not introduced until 1982 when it replaced the C4.
Well this was in an Offenhouser catalog so it was probably an in house designation to differentiate between their early('69-74) 16 bolt intakes and the later('75+) 12 bolt versions.

That makes perfect sense but wonder why they just didn't use years or no. of bolts used?
"No such thing as a 351K .. Where do people come up with this crap?"
That's what I'm trying to determine.
There were two major changes that I know of in the 351W in the early days, the deck height and the number of bolts in the intake manifold. Interestingly, I have intake manifolds with the same casting alphanumeric (D1JE-9425-BA) machined for both 12 bolts and 16 bolts.
Perhaps it would have been better if the change level L1, L2, L7 etc. had come to be used to refer to the different engines.
And confusingly, Ford didn't even differentiate between the 351C and 351W in the early literature. Come to think of it, did Ford ever use those terms, excluding the Motorsport / Racing division?
Interesting information. I see at the top of the sheet that 351W, C, Spec and CJ are listed, but in the rest of the listings I don't see how one can tell which engine the parts are in reference to.

And what's a 351 Spec, is it a C or W?
Read down the columns where it lists the quantity of the parts to determine which part fits what engine.
The '351 Special' is a 351C since it has a flat engine cover plate in lieu of a timing cover.
Typo. K is right above M on the keyboard. Although this seems unlikely. As someone once said , "beats me".
I would second this statement, for the fact that trying to pump out cheap magazines it would be easy to miss the typo on the original. And all subsequent copies would have it.
