If you're running down the freeway in an MGB at 2500 RPM in 4th OD, you
probably should be more concerned with how you're going to remove the semi /
lorry which is about to implant itself in the rear end of your 'B. My OD only
drops the revs a few hundred RPM, not a couple of thousand. I'm doing at least
3000 RPM (60 MPH) at freeway speeds.
