Patience, Bonz, me thinks it is GM doing the taunting.

It seems this information is designed to get you to hang on to the old Nissan for a while longer because this new V8 won't be ready for a year or two.

Having read the article I am asking two questions. Where would that oil filter end up in a typical 4x4 application? And with all that hot exhaust gas getting channelled into the middle of the engine will it overheat?

Overall it looks good but I think I might hold off slipping one of these things into the old Nissan until someone has put a few miles on one out in the bush.

I am not saying I would not like to have a play with one.

I would certainly volunteer to do a bit of testing. Especially if GM want some reliability testing done in harsh Australian conditions.

I can think of a number of harsh Australian places where I would be happy to test the new GM product. I just don't want to pay for it.

Can anyone offer some more explanation on the following quote;
"The main bearing caps are precision-fractured ("cracked"). This novel application of a feature that is commonly used for connecting rod big-ends enables closer crank-to-bearing tolerances with greatly improved assembly accuracy".

This procedure has been in vogue for more than 45yrs. in high performance 2 stroke engines. (big end journal)
I think (STBCH) that the Landrover td5 employs the same principal in its big end journals.
For years now, many high output engines in earthmovers have been of a "throw away" concept.
It is cheaper to replace the donk than rebuild it. Modular construction simplifies, minimises cost, when its done its 10-20k.hrs. just replace.
Read recently that the country with the largest output of Caterpillar OEM is China with a workforce exceeding 25000.
We are really just a flyspeck on the screen.

Yep its the 2010 4.5L V8 Duramax diesel for the half-ton Chevy's. My wife and I are looking at waiting to get our Tahoe or Suburban with that engine, will probably come out in 2009. Has at least 230kw/700Nm will be hooked in to the 6L95E 6 speed auto. Supposed to give the Suburban 28mpg on the highway. I will be at the Utah Auto Show next week, and the Suburban Z71 Concept with that engine should be there, I will get some pics if it is.

No worries, will do (if it's there) by the way, Ford have a 4.4L V8 coming out for the F150 and Expedition (it's based on the Land Rover 2.7/3.6L engines) - would be similar to the GM Motor.

Dodge have the new Cummins engines coming out for the Dakota and Ram 1500 pickups and the Durango SUV. A 4.2L V6 and a 5.6L V8. The latest I have read on the Cummins 5.6 V8 is 260kw/800Nm - would be nice in the Durango, seeing how the Hemi 5.7 gets crappy fuel economy (17mpg highway in the Durango) the diesel V8 Cummins has been reported to get 25mpg in the Ram 1500 on the highway. I will get back next week to report whats at the Auto Show (Utah is a part of America which is big on the pickups and large SUVs so I am hoping a lot of this stuff will be there)
