My understanding is that the differences between the Gen 3 & 4 6.0 engines is almost nil (save the passenger car engines).

 

It doesnt make a case for a solidly engineered truck V8? It's strong enough to handle 1000+ horsepower (I've actually seen up to 1500 with a TT setup), yet refined enough to be placed in a luxury SUV such as the GX470 and LX470 and cars such as the Lexus GS400/430 LS400/430 and SC430. So which other truck motor (as I said other than possibly the Titan which I don't know enough about yet) can match such claims? Just about the only the the 4.7L i-Force lacks is out of the box power (which will actually be fixed in about a year with Toyota's revised i-Force using VVT-i and an extra .6 liters of displacement)... it's definetly behind the times in that regard with around 245hp and 320 pounds of torque. However we aren't talking about out of the box power, we're talking about forced induction in a sports truck.

Care to make a counter-case or are you just attempting to stir the pot?

And nope... the absence of OHC does not alone take something like that out of the running, although DOHC 4-valve per cylinder engines do tend to take a liking to forced induction more so than a lot of pushrod motors.

 

When do the Silverados get Gen IV V8's, I'm guessing they will wait until the new model comes out for '06. I know the '05 Trailblazer/Envoys get DoD 5.3L Gen IV V8s.

 

Yup. There are certainly afew revisions...for example, the GenIV is machined to accept DoD. But I just don't see how they can call them next gen powerplants.

 

Anecdotal evidence about supporting 1000 hp in supercharged boats does not indicated the methods by which it was designed. And strength and smoothness/refinement are not counter-operative. In fact, rigid blocks, strutural oil pans (rather than sheetmetal tubs attached just to hold oil), all help make engines more quiet because it reduces the ability to transmit noise/vibration - think of all the surfaces as little speakers.

As for a counter case, well, I wasn't there for the development of the Toyota V8, nor the current Gen III/IV (though I know much more about it than I do the Toyota), nor the Ford Modular line, nor the 'hemi'. Were you? If you want to call it stirring the pot, ok; I was *sort of* being playful, while pointing out that you made a claim that seems a little strong.

In other words, you could have said that Toyota already offers a dealer-installed blower for that engine, so it would be a good choice to use in a Lightning fighter, and your point would have been perfectly made. I just raised my eyebrows a bit at your claim that it is the most solidly designed truck V8 (admitting that it could be), and took the chance to poke a little fun at your Toyota worship.

As for OHC responding better to blowers, perhaps from a breathability standpoint, but not from a strength standpoint. Besides, just ask John Force about pushrod engines with blowers.

 

Personally I think that truck is a joke when compared to the SRT-10 and the Lightning, but it is obvious that was not what they are going after. If they are, they seriously need to rethink their thinking of eXtreme. I also, personally, think this truck is one of the uglest out there. It looks more like a box on wheels.

 

Hrmmmmmph......

You do of course realise that the SRT-10 will cost *TWENTY TO TWENTY FIVE THOUSAND DOLLARS MORE* than the X-Runner.

 

No one ever said that speed was cheap.
