I have to disagree with that - take a current F1 V8, at 2200 rpm it would probably stall in a Crossfire. It's more about displacement - a larger capacity V8 will have more torque at lower revs and perhaps not rev as high, the 2.4L Honda V8 revs to 19,000 rpm.
I if we assume all the indicudual cylinder displacements etc are the same, ie the V8 has 33% more displacement that the V6 the statement is OK.
PS - 2,200 sounds about right - puts the revs at 2,570 for 70 mph and around 5,700 for 155 mph? Might even be a little on the low side, have to check next time i go out - probably at 60 or 70, not 155.
