I have been told that running an engine, under load, is really not good under 2000 RPM's with an cam upgrade.....I'm talking 1500 - 2000 RPM's

Any information pro or con to this ?

it lugs the motor and bucks a little, get a tall gear and you wont have that problem.

or a proper tune.

More to the point of my question; is it hard on the engine itself ?
.....not interested in symptoms but the effects.

I'm sure it isn't good. But I have never heard of an engine that actually died because surging or bucking caused a mechanical failure. I think it is more annoying than anything. A good tune will not always help. I have been tinkering with the problem for awhile, and I can't nail it down to spark, fuel, idle airflow, or a throttle transition problem. It is a real PITA.

Yeah, my car was tuned with my 1st cam, and will be tuned with my new one, but curious if driving down the highway in 6th @ 1700 RPMs is harder on the engine than running 2300 RPM's in 5th gear.
I was once told that driving below 2000 RPMs is not really good for the engine.

I believe that.

I don't see anything wrong with cruising below 2000 rpms. I do it all the time, but I do downshift to pass!

Nothing wrong with cruising at 1800 or so rpm here and there. Just as long as you do some WOT here and there too.

A motor that spends most of it's time on light loads and at low rpm are more likely to have bore glazing problems down the track.
