I came across this video the other day (via VisioRacer) while browsing around YouTube. It’s a compilation of some interesting and unconventional engines from cars, motorcycles, race cars, and even airplanes. Neat stuff– and it reminds gearheads like us that there’s more than one way to create an engine. Give it a watch. My favorite is the Honda straight-six motorcycle engine. What a noise! Turn it up and have a listen.
