Yeah modern internal combustion engines are a true marvel.

It is often said that the most incredible thing about the internal combustion engine is not that it works so well, but it even works at all!

Man they were revving the pee out of it.
Wonder why they use the little rocker type things between the cam and valve. Why not shim over or under bucket like others generally have? (can you tell Im not an engineer?)
