One of the "high tech/high dollar" You Tube videos of a twin turbo stovebolt engine also includes using a roller lifter camshaft with needle bearings in the block. Also a Wayne type crossflow aluminum cylinder head and computerized port fuel injection. I think that's a step or three too far on an engine design that's approaching its 100th. birthday!
