How to build a 12 cylinder Boss engine from two 8 cylinder engines. First take two printed 8 cyl boss engines do lots of measuring and careful cutting and sanding that is most important to make sure the pcs, all match up right. Then comes thinking about the accessories and how to fit them to the new long block assembly. On this one a
hand made timing cover, fuel pump, injectors, air scoop and headers. Twin printed magnetos to make it easer to run plug wires, plus it looks kinda cool. The air scoop is two level the lower opening feeds the front 6 cylinders and the top the back 6 so in theory all cylinders would be evenly fed air. The engine build was a just because i wanted to but it eventually found a home in sand rail Helter Skelter.
