The strongest as far as block strength will be the Iron-based LSx, but that is only a block.

I have never heard of a GM OEM production motor called a LS7-R (unless it was from the American Le Mans cars).

As far the other two (the only complete motors you listed) the LS9 is the most powerful.

From your list obviously the answer would be LSx, since its only a block and not a complete engine you could potentially build it to fit your desires.

The LS9 would have the highest power output if thats what your after but is essentially the same engine as the LSA only w/ a bigger supercharger at 2.3L compared to the LSA's at 1.9L

The LS7 R you list I'm assuming is the engine out of the C6.R race car and to my knowledge isn't a production engine you can buy. But if you wanted the highest NA powered LS engine, the LS7 would be the way to go I guess.

If you just want higher hp why not just mod the stock LS3?? I mean it starts out at 426hp stock which is a pretty good starting point w/ great potential imo. None of these engines can be had in a Camaro from the factory and all would be extremely expensive to buy outright esp. w/ buying a brand new car unless you have tons of cash. Or are you just wanting bragging rights or something of that nature?

I will keep the LS3 in there for a couple years maybe lightly mod it, but an little bit further down the road im looking at putting basically the fastest GMC motor i can in it and heavily modding it. Just trying to get a picture of how much thats going to be. But in a couple years im sure they will have came out with a whole nother bigger stronger motor haha

The LS9 has the highest horsepower out of all @638hp. But it'll be difficult to get any more power out of it.

ok so i guess a better way to state my question should be, which motor has the potential to be the fastest in the 2010 camaro?

Like already said that would be the LS9 at 638hp and 604lb/ft.

Heres a good place to start for general LS info: http://en.wikipedia.org/wiki/GM_LS_engine

There are ZR1's out there with only an intake, exhaust, cam, and tune pushing well over 750hp. Even without the cam they pushing over 700.

Yeah but what I meant by that is that you wouldn't be able to do much to the actual engine. Of course bolt-ons will still make more power but, since it's already a FI engine there's not much else you can do.

Actually, I was under the impression that they were based on the LS3, not the LS7. Thicker block walls out of the 6.2 than the out of the 7.0, for better strength. Or something like that.

So the LS7 isnt a good engine to supercharge because the block is too thin?

Get your flame-suit ready... The LSA is the 560+hp powerhouse in the CTS-V....


Of those in your list, Hollywood, the strongest engine would be the LSX hands-down. That block is good to over 2000hp. Problem is...it's ONLY the block. The "LSX" designation is a heavy, overbuilt, ironblock version of the LS-series engine blocks. You just have to do everything yourself. Boring, heads, etc, etc, etc...

SO the LSX is the best to start with but its not actually a whole motor.. and between the whole motors the ls7 is too thin to FI, the ls9 is basically maxed out, and the LS3 has the most potential? am i correct in saying this?

right on the LSX. right on the LS7. right on the LS3. That's the block that underpins all the other motors on your list. Potential? Hell yes!!

Unsure on the LS9, though. I don't mean to undermine anyone who's posted here...but there are engineers/mechanics who've stared in awe at the spec sheet for that engine. A memorable quote is: "That thing's indestructable!!" With no real supporting experience, I'm going to say that the LS9 will probably do 900hp with minor reduction in life expectancy.

Reasoning?
It's warrantied as-is with the standard 5yr/100,000 miles deal. So you know it's solid. It's also said to have been rigorously tested to 200,000 miles no problem. And everything inside is forged, with oil-squirters...etc....

You can't really say that the LS3 has the most potential, considering it's potential is basically the LS9.Yes there is more power to be had, but if you want all the "potential" out of an LS3, just buy the LS9. You get your forged bottom end and high flow everything, and at that point its all about swapping parts to find the best combination. Smaller pulleys, cams, heads etc. Now if you want a take no prisoners brute, than absolutely build your own LSX. Over 2500hp capability. I don't know who said building the rest of the motor was boring, but there are few things more fun. That's what I would do. If I had money and didn't mind breaking things here and there. Which I don't. All I need is money.

kinda off topic-ish but does anybody know if the ZZ 572/720R will fit??? And if so how much alterations will have to be made to jam it in there?

There will be plenty more potential found in the ls9. Also there are ls7's running the TVs blowers with over 700 rwhp with no problems. I know of a bigger one in the works.

Basically this is a stupid question. The LSx can go to the largest displacment so it will always have the most potential.

LSX 454 is a complete motor and puts out 620 N/A HP, perhaps this is what you meant. And would IMHO be the strongest motor out of the box for the money. And the LS9 with bolt-ons and pulley could easily see 800hp.
