Ambitious newby

Well I took some of your suggestions and made some changes to my model.  I staggard the cylinders, increased the stroke a bit, made the intake ports longer than the exhast ports, and completely redesigned the crankshaft and crancase, including some counter weights.  I still need to redo the manifolds and induction system as well as add injectors and systems for cooling and oiling.  I wonder if one could design the lubrication and cooling systems as one system.  As in oil cooling, running the oil through a radiator and such.

You still seem to have the crankshaft running in bushings, assuming that's what the white pieces are? Surely you would want to use proper bearings, or is the temperature too extreme, doesn't seem likely? Fitting bearings seems a lot easier than making bushings and getting them all aligned.
