Speed-O-Motive Racing Pistons 1946 T-Shirt

Speed-O-Motive got their start manufacturing custom pistons for flathead racing engines, but eventually began distributing speed parts and offering high-performance engine rebuild kits for pretty much every V8 application out there. If you couldn't swing by their Los Angeles area shop, you could mail order your parts, even complete engines after they begin offering turn key balanced and blueprinted crate racing engines. These crate strokers all ran Speed-O-Motive racing pistons, and the rest of the build leveraged top shelf goodies from other manufacturers.
