Thanks that may help a bit, but I am still looking for slightly more in-depth detail of what I have seen already. I was looking moreso for valve, crankshaft, and piston dimensions, and a better idea of what goes on inside the engine itself. I will soon have access to a real engine to measure off of, but if there was anyone who had some sort of drawings or tables of information of the engine's internal structure it would make things much easier. I have found some pictures of cross-sections that provide the layout, but they all seem to lack any kind of dimensions. Thanks anyway
