Many of us have built engines for our hot rod projects, but the actual description should be “assembled an engine” because we are starting with an existing engine. Longtime Southern California hot rod enthusiast Roger Butzen has taken this process one step backwards though; building the engine from scratch. He machines them from raw metal; albeit in a desktop size.

These miniature recreations of a blown Cadillac / Chevy hybrid, Chrysler Hemi, 4-cylinder Offy, Harley big-twin and current project a Ford Flathead V8 are fully-functional running versions of their full-size counterparts. Roger created them from raw metal scaling them down from full-size components and available technical data.

Countless hours have been spent on each one of these recreations and the accompanying photos show what the finished engines look like. But they are not just display pieces; you can watch them start up and run by playing the attached QuickTime MPEG videos of the blown Cadillac / Chevy hybrid, Hemi, Offy and Harley. Video of the Flathead in operation will be added to this article when it is available
