what is a safe cruseing rpm for highway

i'm taking a long roadtrip and i'm going to try not to blow up my jeep in the process. i have a good running 304. the speed i'd like to drive is 65. my rpms are around 2300 -2400. is this to high of an rpm for driveing long periods? it has 100,200 miles on it. but seems to run strong. has no valve clatter or nocks or pings runs nice and quiet. when i say long periods i mean like 8-10 hours.

<font color=purple>I'd personally say you're on the upper end of the ideal range - meaning, you're fine now, but more RPM's than that would be starting to push the efficiency into a gray area.</font color=purple>
