Our friends managing Summit Racing’s Facebook page and other social media accounts alerted us to their #EngineThursday post on Facebook, which led to more people than we could account for sharing their awesome engine photos.

You can see all of the photos in the comments of that Facebook post, but in the meantime, here are a bunch of engine photos that caught our attention:
