ok im not stupid and i totally understand engine setups such as Single overhead cam and dual overhead cam, but why when im reading about 4K's im hearing things like "its a pushrod style engine". ok, im pretty sure its just a single overhead setup. Or is it totally different to what i thought, and if so, how it differs?? anyone have any pics, like comparing the 4k with another type of setup?
i cant even believe im asking this because it is such a basic question
