Let us beef up the bottom end

Let us adjust how heavily built the crank, conrods, and pistons are, for things like realistic heavy truck engines (or super high power hypercars
).
Basically I'm envisioning like a slider.
WIth stock in the middle, one extreme will be +max torque +max rpm +weight +cost +longevity -responsiveness, the other extreme being the reverse. Should probably also increase/decrease smoothness in engine layouts that aren't inherently balanced. I see this as allowing for a wider range on engines to be built, as gives a fun, simple mechanic into really letting us build the kind of engine we want, from a super "built" tough-as-nails stump puller (Think the legendary GMC Twin-Six, many of which ran for decades in stationary applications driving well pumps), or super lightweight racing engines that only need to last for perhaps a few dozen hours.
