RPM question

This isnt really an issue....yet. but i was wondering if anyone knows the red-line for a 73 318? this may be a stupid qestion, but all i know is.
higher rpms=more heat=more wear= bad.

but if im ever in the situation on the highway like, say a semi jackknife right by me and stuff starts blowin up and flyin everywhere, i wanna know what my limit would be, givin thats a unlikely situationj, i also wanna know where to puit it on my tacho just because.
