I have seen in a couple places that people say an M42 is pretty well built-up straight from the factory, and that not much more can be gotten out of it - NA, of course.
Why is that, exactly?
What -can- be done with it, that's worthwhile? Would port'n'polishing the head do much? Extrude honing the intake manifold, like an M20? Can you stroke it much (I realize there's a factory 1.9 liter...) ? More compression? Cams?
Maybe Stu can answer this... ?
Thanks,
