True flat top pistons
6.0L of meanness!!
Just need to find a totalled out 05/06 GTO
I think that would be a MOST fun swap...hehehe

don't like the 347's tho...too much stroke and the wrist pins are too close to the oil ring on the piston and they fail more easier.

The gearing and drivetrain loss doesn't matter to the question at hand. The numbers change, but the powercurve will always be identicle.
Regardless of where you measure your horsepower, or what anything on the drivetrain is doing - the entire powercurve will still exactly follow the engine power curve to the letter.
No matter what gearing, differential, wheels driven, transmission gearing, or wheel size. The question "when does the engine stop making power" is answered by horsepower, which is a function of torque applied over both time, and distance. Horsepower peaks at 4800rpm, and falls off from there.

Sorry for the misunderstanding.

If they dont take their 3vze to over 4000 they need a good swift kick in the ass. lol Seriously lugging the engine is doing more damage then revving it will ever do...

Not putting down your efforts or anything, but I gues I was looking at more of an "everyday" point of view, where gearing and weight do make a difference.

Okay, by 'seat of the pants' - if I'm driving up a mountain road (we have steep hills around here,) say in third just loafing along, it pulls nicely above about 2000 rpm. If I let it drop below about 1800 it just loses all it's "oomph." I like the low end that it has - the old 22RE NEVER could do what the 3.0 can do, on the same road I would be shifting down,shifting up, shifting down constantly.
Alternately, when pulling onto the freeway and gettin' on it - the power rush starts to come on around 3000-3200 and feels really good from 3800-4500ish. I really don't rev higher than that as it doesn't 'feel' like it likes it too much.
The 3.0 does not make a lot of power (as we all know) but the power that it makes works - it's usable. Smooth torquey power available above 1800, nice kick above 3000. The same characteristics but 100 hp more would be perfect.

Because I'm bored, I will post my butt-dyno power curve.
Idle-2000RPM= no guts. 2000-3000= pretty damn good torque. 3000-4000= holy moly surge of powah! 4000-4800= power trailing off. 4800-5500= only useful for revving out in 1st gear so the shift to 2nd is right in the sweet spot. The 1-2 shift is a HUGE leap in gearing. My first was made for crawling.
So to answer the original post about when the 3.0 stops making power--4800RPM.
We will see when my turbo 3.0 stops making power though. I have a funny feeling it will pull to 6K.

Did you see the thread a long while back about that - amazing how many people refused to believe it takes fuel (in the form of engine horsepower used up) to run the alternator...

Oh and not only does it provide my amps with sufficient power, it also DECREASES fuel usage, acts as a turbocharger, intercooler, AND stops receeding hairlines! LOL
hahaha ok no more Scientific America magazines during Miller time...

Let's rephrase the question to "practical power."
My normal shifts are at about 2200 rpm.
My power shifts are at about 4000 rpm.
Sure you can get a little more above 4000 rpm, but the more you strain an engine, especially this engine, the shorter its life. I have 232,000 on mine driving like an old man, and if you do a search you'll find plenty that died early lives. These engines throw rods and blow head gaskets. I think at least part of the equation is how much you try to extract every last drop of power.
If you want power, you might want a couple more cylinders or a couple thousand pound diet.

Its not worth the thousands you have to put into it just for merely 60hp or less. and the head gasket? they should have recalled these whole motors and scrapped em..
