The major Difference between the LS3 and the L76 is power. I'm no expert on the details, but the L76 is 6.0 Liters, and 367+/- hp. The LS3 is 6.2 Liters, and 428 hp.

They both have DoD, or Displacement on Demand. And I think they both have VVT, or variable valve timing. The L76 in by no means a Bad engine. 367 hp in a car is nothing to scorn. I think the biggest worry is why settle for a "weaker" engine when we could have 60 more horses. Honestly, I would be more than happy with the L76. I would like to have the LS3, but if that doesn't happen (though, I think it will) ...

I know for SURE the L76 has VVT...see that long article I posted...But I haven't heard whether the LS3 has it or not.

Honestly if camaro doesn't come in LS 3 i won't buy one!

Selfish yes. but why the hell would i spend that much money on something i don't want. when i could buy a 3 year old GTO and have a better FASTER car!

If GM puts anything less than an LS 2 in the camaro they need pissed on. and may mustang win the war!

Sadly i figure the first year will be pretty shitty cars without the best V8 even being available. just like i figure 09 or 10 the G8 will come with the LS 3 in a GXP version.

If they are going to dick me on the engine i'll go to corvette or a GT500. i want a minimum of 400 HP in a car not some half assed engine from a truck.

The L76 is being put into the G8, it's no longer a "truck engine". And I'll say it again...we live in a world right now of lotsa hp, more hp, and even more hp...376hp...IS A LOT OF POWER. Sure, 400 would be nice. but the L76 is nothing to snort at, either.

In any event. I doubt the LS3 won't be in the Car...it makes too much sense to have it in there.

If the ls3 doesn't make it the first year for some reason i'll just wait it out. Eventually it will be an option and it just gives me that much more time to save even more money and buy the best camaro that GM has to offer. So either way it's a win/win for me cause i got all the pateince in the world at this point.

Also i though about this earlier....like with the GTO i'm sure some company will get a hold of one of the camaro's and just go nuts with it like the RA6 GTO. http://www.anthemmotors.com/PontiacGTORA6.html

That's pretty awesome! I'm sure they'll pick up the Camaro and mod it. I mean look at the car! How can you keep your hands off of it?

I know it isn't a "truck" engine but why not just use the LS series engines leave it in the trucks. is it cheaper to build or something? I would probabally be buying a G8 if it came with an LS2 or 3 but 360 HP isn't enough for me in that car, ( my buddy just bought an audi S5. so i'd be beat before i started lol

Using a higher grade fuel than required does not improve performance. Theres no ultra simple "upgrade" like that. 92 doesn't equal "fast" it just deals with the combustion of the gasoline mixture. Using 92 in a car that requires 87 will do absolutely nothing, except maybe eventually cause some carbon build up. Don't confuse 87 with low-grade gasoline.

Absolutely right! But I think what he was getting at (correct me if I'm wrong) was that the cars he owns, at least the foriegn ones, required higher grade gasoline to start immediately. And now that I think of it, I mentioned that my 'Maro runs fine on regular-grade gas (87)...it does...but it takes 20 seconds at least, to start up, it also involves some pumping of the gas pedal (carburator)...

I agree.....however the higher the piston compression ratio the higher octane fuel you ought to use. I know that if I use less than 97 octane in the vette there is alot of pinging going on under the hood. Granted it is not the stock motor under there and the idle may be set a little low. It just runs better on the higher octane stuff. Runs superb on 107.

Very true. I just mean to point out to people driving stock Civics, Cobalts, and Ford Rangers that putting 93 in won't make it go faster. I've actually got plans to stroke the 4.0L I6 in my Wrangler out to 4.5L, then bore it .030 over for a grand total of 4.6L. When I was in the shop discussing lift plans, we got to the topic of engines. One guy insisted that the octane is determined by the displacement. I kept trying to tell him that it was based on compression ratio, but eventually I gave up.

The exact compression i don't know. If I had to guess I would say better than 12. In a nut shell (my uncle had this put together balanced and blueprinted so I am not sure of specifics) it is a 350 block, bored out (I assume .40 over), oval track racing cam, aluminium racing heads, solid lifters, hi rise aluminium intake, Holley double pumper coupled to four speed manual transmission and all neatly packaged in the body of a 76 corvette. He said he had it dyno'd and it came in at over 500hp. I had first shot at buying it from him when he could no longer push the clutch pedal in (favorite nephew). Oh and it red lines where the stock tach has no more numbers.

No wonder you need 97 octane with a 12+ compression ratio! :eek: That's one heluva car! You hang on to that!

12 + is just a guess on my part, but it wouldn't surprise me. ....Forgot to mention the 3" hooker headers w/dumps. It is funny....on gravel where the tail pipes point down at idle the smaller gravel gets puffed away by the exhaust......fun to drive!!!!
