Anyone read Sept 4th Autoweek on the GM smallblock?

I just recieved the Sept. 4th Autoweek, and was reading the news section. It was an article about a new 3-valve V8. 2 intake, 1 exhaust, bumping power to 470 hp at 6700 rpm and 385 lb-ft at 5600 rpm. Could this be the engine going in the new Camaro?:) Just thought it was an interesting article.

Sounds about right. ;)

what displacement? 6.2L?

So the 3 valve small block lives.....hmmm I thought this engine was cancelled.

Hmmm 470 hp... doesen't sound like a "base" V8 to me.

385#tq? Seems kinda low doesn't it? Maybe you meant 485?

Ya Rly'

Hmm...Will the super Vette carry 3 valves per cylinder AND a supercharger?

I'm not sure if I'd believe all of this 3V stuff.

I pretty much quoted what was in Autoweek. It was a 6.3L, and maybe Autoweek got some wrong info on the torque. Autoweek said it is all ready for production, but GM wasn't releasing any info on if it was a car or truck engine.

1.I thought it was gonna be a 2-valve?
2.I thought it was gonna have a little bit more hp?
3.I thought it was gonna have way more tq?

70hp bump isn't enough? Thats about the difference between LS1 and LS2.

From what I've read, I thought that the base v8 would be lower, and the Z/28 would be higher than 470 (even if only by a few hp).

From what I've read, I thought that the base v8 would be lower, and the Z/28 would be higher than 470 (even if only by a few hp).

Dunno, first it was suggested a midlevel V8 would be 5.3, 300 and something hp... that was of course not enough...

So people are saying 300 from 3.5, 400 from 6.2 and 500 from SC 6.2...

280 from 3.5, 380 from 5.3 and 480 from NA 6.2 seems a lot more likely to me, for a variety of reasons.

why the huge discrepencey between torque and hp, that doesnt sound like gm small blocks of late if u ask me

Powertrain changes have already occured and I wouldn't be surprised if changes are still to come.

But my best, educated, guess, right now is:

Base - 3.6 V6, 285 hp.

SS - 6.2, 400 hp.

Z/28 - 6.2, 400++++++ hp, (SC?, maybe, but I hope not.)

base = 3.6L 300HP
SS = LS2 400HP (or LS3 or a different 6.0L)
Z28 = 470HP 3v 6.2L

this would be a cool line up. Save he S/C 6.2L for a ZL1 @ $40K+

base = 3.6L 300HP
SS = LS2 400HP (or LS3 or a different 6.0L)
Z28 = 470HP 3v 6.2L

this would be a cool line up. Save he S/C 6.2L for a ZL1 @ $40K+
I could live w/ those. Would prefer 500+ just for the h*ll of it, but this lineup looks feasable.

Is the 3.9 OHV out of the picture now? Interesting that Guy and Charlie are leaning two different ways on this supposed 3 valve V8...

Spinning a small block north of 7000 RPMs sounds like a lot of fun to me :) If they're looking to recapture the idea of the old high-reving Z/28 (302 ci) then this sounds like the way to do it.

See, I was thinking that somewhere around the 480HP would sound right for the Z/28 model. Anything more, and then your pushing into Z06 domain.

So, everyone is sure that the Z28 is going to be top dog?

so what your saying is were gona go from a 6.0 with 400hp to a 6.2 400 hp and this makes sense to you how:D

we went from 5.7 at 405 hp (ls6) to 6.0 with 400 (ls2)

my best guess as to why is better power curves and fuel effeciency/ burns cleaner

If the new Camaro isn't a torque monster, it will fail.

http://en.wikipedia.org/wiki/GM_LS_engine#LS6 yes but in a matter of speaking it was a more robust engine. where as the ls2 had less strain on it. the ls6 was only used in the z06 and the v serious i belive.

385#tq? Seems kinda low doesn't it? Maybe you meant 485?
485tq @ 5600rpm would give 517hp. ;) 385lbft sounds about right assuming the torque drops off a little to about 370lbft @ 6700rpm giving you 470hp.

I am getting tired of the "If the Camaro doesn't have XXX feature it will fail."

Your arugment makes no sense and shall be ignored by myself and others. Thank you and have a nice day.:)

Had these pics from a while ago, not sure if they are the same exact head, but they look close to the CAD image in the 5th gen thread

Yea, it was a little broad and harsh, but what I mean is I just can't see a Camaro having those numbers and delivering what we want....100 less torque than horsepower, what will that drive like iif it were to go in the camaro, which will probably be slightly heavier than the 4th gens??

If the new Camaro isn't a torque monster, it will fail.

:think: 385 lb-ft is a lot of torque.

would you rather have 400HP and 385tq or 470HP, the same torque and 7000rpm readline? 385 lb-ft is more torque than a Camaro has even had since the 1969 ZL1

Shows what I know about cars....I just understood why I was wrong....you don't need as much/more torque than horsepower, only enough, and yes 385 is a **** load. Right? I've had the incorrect idea that a car isn't fun to drive when it has less torque than horsepower, but I've now realized that those cars I've been thinking of are lower-end imports that don't break the 220 tq mark, like hondas that people think can beat your LS1.

Maybe that's why I'm in autobody and not auto mechanics =P.

those pictures look like the heads are on a truck engine

What worries me about this is the fact that the Camaro wouldn't offer anything in the 300 HP range which is where the mustang GT is. Some people want a V8 but having to get a SS and 400 HP is not what they want...it isn't what I want. I want my V8 somewhere in the 350 HP range and I think a car like that could sell VERY WELL in todays market.

I think GM might do it like they did with the Corvette. Base Corvette has 400HP, then the Z06 has 505HP. Maybe GM will do the same, offer the base V8 around 350 or so, then the top of the line V8, around the 470 mark. Just my thought on the situation.

Believe me, there are LOTS of people that think the same way you think. However, there are also a lot of people who cant seem to understand that idea either. They think that just because there is a Camaro model with less than 7 million hp that it will fail.......

I don't think it is so much about HP as it is about price and gas milage.

I'd like 30mpg and a price under $27K with a V8 that can do at least mid/high 13's low 5's 0-60. If the can that with 350HP or 400HP it doesn't matter to me.

If I'm going to spend CTS money, then I'll probably get a CTS.

Call me crazy but, a very well priced Camaro with a V8 that gets atleast 30 MPG with AFM and around 350 HP with an 6 speed manual or auto would/could be a great selling model for Chevy and the Camaro. This has to be reasonably priced and on par with the mustang!!!

If GM can offer a Camaro like that at the same price or just under cutting the Mustang GT, it will be a success.

Don't worry about gas mileage being worse than the mustang..... Seeing how 75% of them get 4.10 gears in the future!

From what I've read, I thought that the base v8 would be lower, and the Z/28 would be higher than 470 (even if only by a few hp).

That is what I heard.

420 and 500ish

THat is pretty much the exact Camaro I'd be looking for.
