Good point. (all) I think all small cube engines need it all to work well. A 360 has enough cubes and torque even with low compression to overcome what is needed to make a car perform. Say a Dart or Duster is a dog with a 318 with say 150 horse at 3000 rpm where a 360 may have 230 at that same rpm. That's quite a performance difference. On the street with a stock or near stock converter Most of the performance is needed between idle and 3000 rpm (or so). That's much easier to get with a 8:1 360 than a 318.
