Hardware Kit and Build Support by MakerRx
Before overhead valves took over, there was the Flathead V8 - raw, simple, and legendary. This 3D printable scale model brings that piece of history to life with moving pistons, cam-driven valves, and a crankshaft.
Originally modeled by ericthepoolboy. We teamed up with Eric to put together a hardware kit for anyone who wants to skip the parts hunt and go straight to the fun of building.
To simplify the build process, Maker Rx collaborated to create an official hardware kit. It includes bearings, belts, fasteners, rods, magnets, a DC motor, and more. Everything you need besides the printed parts.

This model is part of the Maker Rx engine series. Explore our supported kits including the EJ20 Boxer, LS3 V8, and more. All include free downloads, hardware kits, and instructions.
Original design by ericthepoolboy. Maker Rx partnered with Eric to provide a complete hardware kit and build documentation to make this project accessible for more makers worldwide.
