Funny, that image has been my wallpaper on my laptop for a few years now lol

You have some information backward. The F20c is over square. It’s a contributing factor to its high rev, low torque nature. Also, over square allows an engine to rev higher, which will generate higher piston speeds.

Undersquare is sometimes referred to as a stroker motor.

I had to do a double take when it had the F20C on the same page as engines with a design that typically output more torque, then thought...what the heck do I know, maybe :shrug:
