New chevy motor in production?

My brother test drove a truck today and brought it by so I could take a look. It was a 2000 or 2001 Gmc truck ,maybe half-ton 1500 but I wasn't paying attention because the engine ID was distracting me.On the throttle body it indicated "vortec" -of course ,,but under the hood was a sticker that said 5.3 liter!!? Is this a new production engine? Or did they bring back the chevy 307?? It was a pretty torguey engine though.

Re: New chevy motor in production?

just a couple years behind are ya?[img]/wwwthreads_images/icons/wink.gif[/img] Just kidding man, those engines have been around since 99 as well as 2 other new engines, the 4.8L and the 6.0L. All are very good engines are put out more HP and Torque than there older Vortecs did.

Re: New chevy motor in production?

the next six cylinder that will end up replacing the 4.3Ls is a pretty crazy piece of work. Its a inline 6 4.2L. Nice power feel and very very quiet (almost creepy quiet for a gm truck) I checked it out in the trailblazer. Also got a sneak peek at the voltage system all vehicles will be going to in the next few years (complete by 2008) We will have 48 volt systems instead of what we now call 12 volt.

interesting future

Guess I 'am behind. Did GM get bought out by some one? (I didn't hear anything) Is that why they're throwing new numbers in on the engines?

What 48 volts? That would frick everything up like car audio and most anything that is plug in on a truck right? That inline 6 is sweet 275 hp over a measly 220 by the 4.3 vortecs. Kinda sad on how low the trail blazer sits. They should through that 6 in a small blazer.

Just one note about the 5.3L. My friend has a 2000 Tahoe with the 5.3 and I have a 98 Tahoe with the 5.7L. He had (I say had cause I've added a few things to mine) more HP than me. A stock 5.3L has more HP but less torque compared to a 5.7L. I'm interested in the torque not HP.
