Ford 300 Inline 6-Cylinder Engine
George presented this project at the 2014 NAMES show in Detroit—a Ford 300 cubic inline 6-cylinder engine. The engine was started in October of 2013, when George was planning his winter project. The idea came from his inline 4-cylinder engine (the 302 V-8 above) as well as some of the dimensions, bore and stroke. At first, he was only going to add 2 cylinders to the 4 design, but then decided that he didn’t want it to be somewhat generic. So, having worked at Ford Motor Co., he looked at the 300 inline six.
To model an inline six meant that the distributor would have to be mid-engine, and that would require helical gears to drive it. In searching for stock gears there was nothing that would fit the scale of the engine, so George would have to make a set. A contributor on one of the modeling forums came up with a technique for cutting helical gears with a home-made fixture. So, following his plan, George made the fixture and calculated the necessary dimensions for the gears and cutter. Once the gears were cut, he made a small fixture to test the center-to-center accuracy before machining the camshaft. The mesh was almost perfect , so the cam was made in two pieces and the gear was used as a press fit bushing to lock both halves of the cam together.
Transmission for Ford 300 Inline Engine
At the 2011 NAMES show in Detroit, George brought along a transmission he was working on for his Ford engine. The case is machined from billet stock using manual machine tools (no CNC), and was coming along nicely at that point.

George liked to build engines that were not already documented. Being an employee of Ford Motor Company before he retired gave him access to more information than most people. He put over 1900 hours into measuring, drawing, and building this model engine. His first attempts at building resulted in a compression ratio that he felt was too low. So George re-engineered the piston and combustion chamber shapes to get it up to a more respectable 8.5:1 ratio. He also built the radiator. The scale starter and generator are non-functional, but add a lot to the realistic look of the engine.
Artwork by George Britnell
George went to art school for a while, but getting a good paying job in that field was tough. So he ended up going for steadier employment to help support the family. It’s too bad, as he is obviously a very talented illustrator. Most of his work was done with watercolors and colored pencils. He covers a wide range of subjects, from people and animals to vehicles and landscapes.
