Uh................that's because you could not GET a 440 in a 68 RR
The only 440 available in them (at least up through 70, I don't remember later) was the six bbl in "69 1/2"
Is that right?
THAT would be a good reason to not have a price.
So I swear that I have been looking at 440 '68 and '69 Roaddunners all my life... some local sources claim that many of these were probably swaps, but a lot of them could have been "special order." Does that sound right?
sorry but the 440 super commando along with the Hemi were available in the 68 GTX

Good thing the OP didn't ask about the 383 six pack.
Unless someone can prove differently, my research indicates-
The 440+6 was available mid year 1969, and again for 1970 and 1971.
Starting in 1972, a 440+4 was available, but if ordered, the RR became a GTX.
This continued for 1973 and 74.
Except for the Superbird (which WAS available with a 440+4, 440+6, or Hemi, but NOT a 383), those are the only optional 440 engines for the Road Runner I am aware of.
Now someone swapping a 440 INTO a RR was and is VERY COMMON, and if it is then sold, a lot of times the new owner thinks it's factory and doesn't know any better, or how to tell.
I knew this but never connected it in my mind that technically the 440 sport Satellite was really the poor mans muscle car in 68 not the roadrunner. So how many 440 4 speed satellites did they make in 68?
The first column is GTX, notice teh N/A in every other column for a 440 from the dealer data book

I think the 440'sport satellites would have been much more expensive than a 383 RR, and probably close to the cost of a bare hemi RR, the sport satellites would have been a high option ride.
i have never heard of or seen a sport satellite with a 440......a lot of sport satellites had 318 s ....so i think a 383 made them very high option cars....
i have a very optioned out one with a 383 RP23N0E which was a welcomed upgrade from a 318 one
