Something else, even a 6.25 rod with a 4" stroke would not be defined as a long rod motor. By definition, a ratio of 1.56:1 would be a short rod motor.

Brainsboy endorses short rod motors, thats fine, but the rod length(6.25") that Brainsboy argues against is actually SUPPORTED by his argument.

As the article points out, 1.8:1 is the "ideal" compromise between breathing and mechanical stress.
