Default New 6.2l V8

Has anyone read this?

http://www.pickuptruck.com/html/200...ison/page3.html


I know its for the Light Duty P/U's but wouldnt the new Camaro Z28 have something similar to this in HP/TQ or better? Throughout the past, the Camaro Z28 has always had more HP/TQ as far as i can remember. It had more HP/TQ throughout the 90's than the P/U.


Could this be a prediction or an insight as what is to come for the Z28?

EDIT: what do you think about the 6spd auto mentioned in the article?

try this link...


http://www.pickuptruck.com/html/2007...son/page3.html


read towards the bottom of page.


Edit

I dont know why but this link works. As far as the #'s that i was talking about was comparing the 1500's to the Z28. I know that GM put in a 454 in some of the early 90's SWB 1500's but i dont recall the #'s that the 454 was rated at.

Here to make this easier.

"And as six-speed gearboxes deploy, the 367-horsepower / 375 lb-ft 6.0-liter Vortec Max V8 will be retired and replaced with the 403-hp / 417 lb-ft 6.2-liter Vortec V8 across the entire light duty lineup. Today it’s only found in the Sierra Denali. The 6.2 is the most powerful naturally aspirated V8 currently available in the half-ton segment."

So if that 6.2L goes in the Camaro it should be rated at at least 450hp. I'd be happy with that. Then a SC version with 520-550hp, would make it all the more sweet!!

This is what i was guessing. Anywhere from 425hp to 450hp would be good. Now, lets just hope that GM gets it done sooner than 2009! Too bad it wasn't ready for 2007.

The 6.2L they are talking about is the L92.
It is found in the GMC Yukon Denali, and all 3 versions of the Cadillac Escalade.
It's a truck engine. The car 6.2L engine is the LS3.

Is that LS3 going to come with VVT?

That would be badass to have two diff. cam profiles!

i doubt they will use a 6.2L vortec truck motor for a camaro. isn't that an iron block? GM will much more likely use the aluminum block LS3. the vortec isn't a car motor. it's a deep truck sound. the camaro needs the LS3. i for one would be surprised if the LS3 didn't wind up in the camaro - at least some version of the camaro, like the SS or something.

even so, vortec in a camaro? i just don't see that going over well with the die hards, especially with a perfectly good VVT LS series motor sitting out there. people will be pissed if they give us a truck motor. i, for one, will be.

Last time I checked, the truck motors were in the LS family too....

That would explain all the LS1 guys putting 5.3L heads on their engines.

Seriously, all GM would have to do is swap the cam, intake and exhaust manifolds, and the computer and BAM it's a sports car engine.lol

Yep. That's pretty much all there is to it.

but the blind consumer won't see that. what they'll see is VORTEC powered. the average consumer who knows nothing more than the name of the engines will say "oh, a truck motor..." they want to see LSx, not VORTEC, unless the camaro is made to pull around trailers.

i want the LS3 with VVT. not a motor designed for trucks. i want a 7k redline and i want it to pull harder with every single rpm all the way to the red, and i want to see it paired with an A6 that can bark both the 1-2 and 2-3 shifts stock and an M6 that can bark the 1-2, 2-3 and 3-4.

So are you pissed that the vette got the LS3?
It's the same block, rods, crank, heads, and the pistons are the same as the L92 except the valve reliefs and rings. Instead of the truck intake it uses the L76 car intake with a foam shell/cover thingy to reduce noise. The real difference in the heads is hollow stem valves and LS6 springs. Cam is bigger profile but they'll eventually share the dod/vvt stuff. Oh the LS3 has the vette oil pan instead of the truck one. I'm still calling it an LS3 instead of a L92. LS3's don't have vortec on them anywhere.

this further strengthens my point. NO AVERAGE CONSUMER IS GOING TO KNOW THIS.

this is what the average consumer knows:

Vortec series - truck motors
LS series - performance car engines

no consumer wants a truck motor in their sports car/muscle car.

and i want VVT in my motor if it's available.

why would i be pissed the corvette got the LS3?

thanks for strengthening my point.

I thought your point was that you thought L92's were iron block truck motors without the sportscar like alum block and vvt technology like the LS3 will have. And that gm might put a vortec motor in the new camaro. At least that's what it seemed like you were implying.

My point is that the L92 is an alum block high performance engine that already has vvt and dod. And also that the LS3 is based off it. Also I think that gm is not going to let the Corvette be upstaged by the Camaro by giving it a motor with as much advertised power.
I also think it's foolish to assume that gm would stick anything with vortec on top of it in a car. For one reason I don't think the truck manifold would fit under any car hood LOL. Seriously, Holden doesn't call the L76 a vortec max, even though there comprised of mostly the same parts. I doubt gm would do the same over here. I don't hear the Aussies bitching about having a truck motor in there Commodores and Monaro's!
Even if it was the L92 motor they're not gonna call it vortec, that's reserved for trucks. And if they did use the L92 in the new Camaro you wouldn't be disappointed. It's almost an LS3. Besides I'm hearing the new car will be a pig, so they may have to put a truck motor in it to haul it's fat *** around LOL! All bullshit aside, A good analogy would be the B2L and the L92. L92 was 350 tpi motor in c4 vettes, B2L was 350 tpi motor in 3rd gen f-bodies. The L92 only made 5 more hp mainly because (let me repeat it again incase you missed it the first time) GM WILL NEVER LET THE VETTE BE UPSTAGED BY THE CAMARO IN ADVERTISED POWER. I don't think the new camaro will be any different. Was any of that your point?

The thing is GM's truck motors have been considered pretty hot motors for their respective displacements. I mean where else are you gonna find a 294 cube OHV V8 cranking out over 1 hp/ci. Surely not Toyota, their POS 4.7L DOHC V8 puts out like 240, Ford's truck 4.6L only does like 250-260, even less back in'99 when the LS-based truck engines debuted. The current Dodge 4.7L puts out like 230(albeit like 300+lb/ft), rather pathetic.(HOWEVER the Mopar boys have finally souped it up and the new version is said to be around 280hp....)

Even the 5.3L and 6.0L are generally considered as benchmarks for building a good V8(less so in the 6.0L, but it's here by association...)

The thing is, a lot of people know that the truck engines are related to the 'pure' LS motors by more than just a shiny bowtie badge. It is BLATANT that the LS truck motors are NOT a chip off the old sbc family, rather, refined, high-output V8's that just so happen to be nearly identical on the outside and inside.

More than one hick has taken their first look under one of these trucks' hoods and said, "WTF that don't look like a Chevy motor to me, a-hyuck!" and then gone and hopped on their 10-year old Hewlett-Packard PC, waited for their dial-up to connect and painstakingly researched their truck engine, only to find out that it is indeed a close sibling to the LS1. Said redneck then proceeds to slap Corvette emblems on the sides of his truck, but that is a different story....

The point is, think of it from this direction. GM puts sports-car engines in trucks, not the other way around.

U contradict yourself throughout the post. Plus VVT has been used by Toyota For years.... Do normal people say Keep vvt to the imports? Just because you were not aware that ls series truck motors are loosely designed after their LS predicessors, dont hate.
