The Acura Honda J-series is close to square: 3.5039" bore against 3.6614" stroke, within 4.3%, which splits the difference between a high-revving layout and a torque layout.

Each of the 6 cylinders displaces 35.4 ci (580 cc).
11:1 on aluminum heads is high enough that pump premium or better is normally required.
