Closely resembling the Chrysler 300 ‘Hemi’ from the early 60s this 1/3 scale model has a 1.0 inch bore and .900-inch stroke for a total displacement of 5.65 cubic inches. The engine was made by James Weber, of Riverton, Wyoming in 2004. It burns gasoline or methanol (methyl alcohol) on dual electronic spark ignition and incorporates a two-stage pressurized dry-sump lubrication system. The custom designed Roots type sliding-vane supercharger with dual carburetors pushes the engine speed to 12,000 revolutions per minute.

James spent 5 years in the design and development of this engine and it is machined entirely from aircraft grade aluminum and steel bar stock. He is a self-taught machinist who honed his skills and techniques within his home machine shop. His quest is to educate and encourage others to learn machining and enter into the world of miniature engineering.
