Techincally, they are. I guess if a person is consistantly running 10s and 11s, the perception of "fast" may be altered a bit. The majority of new cars these days are stuck running 16s, so it is fair to say that 13s and 14s are quick. The fact of the matter is that times run and whether or not it is deemed "fast" is really a relative statement to what is being run, which is this case is a 273 or 318. 12 to 14 second times for these motors are quick for them and still quick in the overall grand scheme of things.
Not everybody can build 10-11 second machine, nor drive it daily on the street.
