Gees I dont know about you V8 owners...my Td5 revs to 4500 easily...albeit with a good dump of smoke!

I shift around 2500-3000 most of the time...

Interesting to see all you 3.5 V8 owners are not afraid to rev the little things to the max. These are fantastically underrated engines, I have never broken one and I have taken plenty to valve float

I guess the problem is that to get more HP you need more cubes, and that generally seems to reduce the lifespan of the rover V8 . I have seen many 250K + 3.5's still going, allbeit with round camshafts now, but they get a sound caning regularly and just refuse to give up. Maybe it is the lack of cam lkobes and lift that is the inbuilt rev limiter...?

On average it's at 3k. On a bad day I'll take my 3.5 v8 all the way out to 5k. The gas system doesn't like that much, and I've blown a few air filters out doing that. I need a bigger holley to suck it down!

But how awesome does it sound?!
I believe ours has just over 300k on the clock. It's a bit confusing, since my speedo reads 10km/h over everywhere & has been changed before.

And let's face it. The biggest killer of an engine is revving when it's cold. I never do that. I drive like a granny until the thermostat opens and then nothin' matters. I mean really, let's consider taxis. You cant tell me they dont get thrashed, but, since they're always at op-temp the damage is minimal. I apply the same rule to all my cars.

I'm shifting in the fender at 3000-3500 (actually can't get it much higher than that anyway

Old 3.5 rangy 3000-5000 depending on what was going on

3.9 D1 auto usually goes up to about 5500 if i'm pedal to the metal

Must admit though most cars i've driven over the years has always been shifting around the 3000-3500 range or otherwise when the engine sounds like it's ready for it for a smooth shift.

On the otherhand... the missus shifts in her little mazda at about 2000 and you can hear the car struggling to get moving again, where as up to 3000 and it's all good.

define a good "change" of RPM....

auto rangie on the way to tamworth.... changine at 4-5000rpm depending on the hill and what warp speed i wanted to get up to....

I generally change at about 3000, but that is with a diesel engine.

Some of the Rover V8's need to be regularly taken to higher revs or they get a carbon build-up on the valve stems, which leads to sticky valves - some (not 3.5) are notorious for this.

Now the Disco changes whenever the ZF decides to,most of the time,exept in low range in sports mode

Now the Puma,if you change any lower than at least 3000,it will labour in the next gear
This of course depends whether you are going up,down or on the flat......

It doesnt seem to like being under 1800 rpm,as is with the case with the TD5,and most other small turbo diesels.
