Don't know how true it is but it sure would be nice as long as the price doesn't swell along with the horse power.

600+ HP from a NA 7 liter might be hard to get while staying legal and reliable.

One day I will get a ZR1. Even if I get it before buying a house. Mark my words!
Although, I thought they were going to remove the 7 liter engine.

The current LS7 gets 550hp easily in some other cars (they use it i.e. for engine conversions in TVRs in England, and just a different exhaust gets it at that level of hp).

I doubt the ls7 will still be in the line up but if so could you imagine a 575-600hp zo6 let alone the zr1. That would really give the competition a reason to run and hide.

I'm sure it can but it would have to meet SMOG and noise regulations. If those regulations weren't in place here in the US, I'm sure the LS7 would put out way more power.

Direct injection and VVT can both help with emissions.

Reliability won't be that big of an issue, it would only be about 85 hp/L. GM sells a few million naturally aspirated engines with that sort of specific output each year.

Different countries have different rules & regulations. Plus, the aftermarket has a different set of rules to follow than the original equipment manufacturers do.

Also just read in April's Motor Trend that they are working on a "low cost" Corvette with a 5.3L V-8 for 2015. They were saying it would have a different front and rear fascia from the Stingray. Pretty cool if it's true cause I would love to see a 5.3L in the sixth gen Camaro.

I don't see it happening. Corvette production is limited to about 40k units a year. Thats all they can push through the plant, unless they are drastically improving the build-efficiency as they re-tool for the C7. The Stingray shouldn't have much of an issue maintaining a global demand of 40k units per year though most of its life, which is rumoured to be fairly short. If it can do that, then there is no business case in selling a less expensive C7 unless they cut cost faster than they cut the price (which is very hard to do).

But beyond that, what does Corvette having, or not having, a 5.3 have to do with the Camaro getting one (or not)? If they want to put one in the Camaro, they'll do it. Afterall, they developed the L99 as a Camaro only engine.

Which GM engines put out 85 HP/L? Are they push rod or DOHC?

Nearly all the variants in the High-feature V6 family (3.0L and 3.6L) are between 80 and 90 hp/L, and there are a few in the Ecotec 4 cylinder family are up in that range as well. I don't know the sales numbers for each engine, but I don't think its unreasonable to assume that at least 1 in 5 GM vehicles, worldwide, has one of those engines.

As far as I know, all these engines are DOHC, and any that aren't would be SOHC not push rod. But the placement & number of cams (to my knowledge) doesn't impact engine longevity

I was just saying in general because the Camaro has shared powertrains with the Corvette since 1967.

I'm not saying an overhead cam engine is more reliable or longer living than a cam in block engine, just that they put out more horsepower per liter than a cam in block engine.

Oh ok, I thought your 2nd comment was still related the 1st one I responded to, where you talked about 600 hp from a 7L being difficult to do legally & reliably.
