This doesn't seem to really follow the topic of the OP's thread which was about efficient engines which is a totally different subject.

That's exactly how my car was geared then - at 75mph, in top gear, it's at exactly half of the redline of 8200rpm. The B16 would have been perfectly content purring along at about 2000rpm at that speed instead of 4000 though, and would have had power to spare.
