Details regarding the updated 5.3-liter V8 were limited, but a brief test-drive confirmed it will produce strong torque for truck applications. This engine will also power the all-new 2005 Corvette.

The 5.3-liter V8 is the latest iteration of GM's legendary ''small-block'' V8, and for those of you keeping score at home, this is Generation IV of that model. It has a long and illustrious history going back through 50 years of street and track use, in millions of family cars and more than a few Chevrolet Corvettes.

The first application of the updated 5.3-liter will be in the 2005 Chevrolet TrailBlazer EXT and GMC Envoy XL SUVs, and the Envoy XUV, which is an SUV that converts into a pickup truck. The engine will also be available in the Buick Rainier SUV, but will not have DoD in that model for technical reasons, and of course it will power the new version of the Corvette, which debuts at the North American International Auto Show in January. As you might imagine, details on that version are currently unavailable.

So we'll be going from 5.7l to 5.3 ? Oh the rumors and propoganda.

GM Press Release 10-28

The Gen IV small-block V-8, with higher performance and an array of technical advancements. The Vortec 5300 small-block with DOD debuts on V-8-equipped versions of the 2005 Chevrolet TrailBlazer EXT, GMC Envoy XUV and Buick Rainier. "An automotive application of the Gen IV small-block without DOD debuts later in the 2005 Corvette."

The above posted by Rick Daniel, a forum dealer, in this thread:

New Gen IV eng. info.

"DOD" of course stands for Displacement on Demand.

But, as GM executive Gary Cowger put it: "Think about Ted Williams' unmatched feat from 1941 -- his batting average." Which was .406.

And a 101.5mm bore and 103mm stroke are very close to 406 cu.in.

So, is it going to be 323 cu. in. and 406 hp or 406 cu. in. and x hp?

Only time will tell. And in Jan. we will all know.

JBsZ06 · 11-08-2003, 05:07 AM

56 days I think?

Should be cool.

Will we get DoD in the Vette?

One of the things I love about the Vette is that if I keep my foot out of it, I can commute to work and get better gas mileage than my 4-cyl econobox gets.

Hope they keep that up. Maybe we could see mid 30's highway...

Power on demand will be wonderful if they can perfect it. They didn't do such a good job in the older Caddilacs. But technology has come a long way since then, so we will see. I for one would not buy that particular first generation technology. But once it's proven to be reliable then I would.

Can somebody find a link for the NYT article? I can't seem to be able to find it anywhere.

A 5.3L engine for the nextgen vette and a 5.7L (LS1 or LS2) for the new GTO? Just doesn't seem right to me:(

Maybe GM is saving their new bigger engine for debut in the nextgen Z06??

mwascom · 11-11-2003, 04:36 AM

I would love to see a 427 c.i. option in the next gen of vettes. Would I pay extra, oh hell yes !

Nabbs · 11-11-2003, 06:07 AM

I doubt the 5.3 will be in the Vette, but would expect to see an LS7 in the Z.
