Duramax 4.5L
 

General Motors plans a 4.5 L V8 for light-duty applications which will be built at GM's powertrain facility in Tonawanda, New York after 2009. Designed to fit in the same space as a Chevrolet Small-Block engine, it is expected to produce over 310 hp (231 kW) and 520 lb·ft (705 N·m) of torque. The small size should allow the engine to be used in a variety of applications, depending on market demand, though it would initially be targeted for the Chevy Silverado/GMC Sierra and Hummer H2.[2] Unlike previous Duramax engines, the 4.5 liter will be designed and built entirely by GM, without assistance from Isuzu.[

can't wait to see it in production

Ya other then it uses an Urea system once we can bypass all the emission crap. :U::c:

I can't wait for the 4.5L Duramax in the 1/2ton trucks.

I want one bad!

So do I but they will probably be like $40,000.Why must everything good in life be so high priced?

No kidding, I would buy one in a minute. The thing is you are probably right about the price. Why would you pay 40k for a 1/2 ton when you can get a 3/4 ton for 45k?

Yeah why must they make us pay that much for our diesels?Especially 1/2tons.Oh well what can you do but work work work and pay for those trucks then celebrate with mud running!:c:

I WOULD WAIT FOR THE NEW 4.5 DURAMAX, to get the bugs out, before you buy!!!

You do have a Point Gunman.
