That's true. But there really is nothing special or really much different about a 318 compared to 340s, 360s, and the strokers. It will respond in a similar fashion, it just will make less torque at any given rpm compared to the others.
The "appeal" of the 318 is its reputation as a underdog, and the fact the cores are practically free. It still costs the same or more to build it equally, so there is zero advantage in the real world.
