The LS3 family - Three new crate engines

[OctaneSS/RS]

The LS engine family is expanding once again. This time, we have three powerful new engine offerings to enhance the choices for late-model performance enthusiasts, muscle car and street rod builders, and racers of all stripes.

The three new engines – the LS3 6.2L, LS376/480, and the LS376/520 – continue the LS tradition of breaking new ground for efficiency and performance from a pushrod platform engine.

The LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. The LS 376/480 is an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower! The LS 376/520 is equipped with an aggressive camshaft and GM Performance Parts' exclusive carbureted intake manifold. That's two simple upgrades that add up to 520 horsepower – a 90 horsepower bump over the stock LS3.

Available in early 2008!

Let's hope the 376/480 comes in the z28/SS. I doubt the carb version will make it, lol. Nice news, I guess the different cam profile spec in the second one is the LS3 "hot cam".

:roxor: :roxor:. Hmm the Replacement motor in my Camaro just got a little fuzzier. Dammit GM way to go now I have one more option out of 100 already. :roxor:

Any word on pricing yet?

[OctaneSS/RS]

Nothing firm yet, but I would suspect the regular LS3 to cost a little bit more than a LS2.

The LS2 crate is about $5700 from GMpartsdirect.com ($7859 list)

Man that LS 376/480 would be very nice in a G8, or a 5th Gen! Then all it needs is a big turbo, intercooler, methenol injection, intake, exhaust, and tuning!!!!

[slims00ls1z28]

LS9 would be even better :lol:.

[Mykdiver]

Oh, well yeah! lol

Half the fun is watching some of you guys going nuts on these cars. Who will be the first with a 1000hp 5thgen Camaro?

[OctaneSS/RS]

...Who will be the first with a 1000hp 5thgen Camaro?

Like this maybe?

:D

[Douge]

Seriously, you know some of the first cars will go straight to the tuners. That is one of the greatest things about Camaro/Vette & Mustang. etc... very reasonable and usually fairly easy to mod.

[mdennis10]

THAT IS EXACTLY WHAT CHEVY NEEDS TO DO TO THE CAMARO. IF THEY OFFER DIFFERENT CAMS THEN USING ONLY ONE V8 WOULD BE FINE. DIFFERENT ENGINE OPTIONS IS GREAT AND WOULD MAKE SINCE AS FAR AS PRICE GOES BECAUSE THE CONSUMER CAN ADD TO THE PRICE TAG AND NOT BE STUCK TO WHAT THEY GIVE YOU.:roxor:

[altoid]

I want that 520hp LS3 in a Miata. :D

[OctaneSS/RS]

I want that 520hp LS3 in a Solstice. :D

Fixed. ;)

[altoid]

Fixed. ;)

%s/Solstice/Miata/

[NemeSS]

imo for 8k$ i will build a LSx 6 bolt based motor, with forged pistons and stroker crank along with top notch heads, and intake.
4.185 (bore) x 4.125 (stroke)=454 LSx with LS7 type heads
just sayin'

If they come charged from the factory with a stout bottom end I dont think that will be a problem :lol:.

[3whiterag]

We have run some special prototypes of the LS3 engines and you would not believe the hp. ratings!:roxor:

[Cobalt LT]

I'm looking at a Twin turbo STS style system with Snow performance injection fully Ported heads and a slightly bigger cam. true dual 2.75" exhaust and headers. i think that will do it. maybe to the tune of 550whp.....

That would be sweeeeet if chevy offered that for the Camaro.
I look at it this way would chevy come out with 360 plus for
the G8 so that tells you that the CAMARO would have more
right???
:patriot:

[slims00ls1z28]

In theory yes until they announce it though its nothing but educated guesses. They have shown the car now we need to see what's underhood!

[BuellinBeef]

Ok, dumb question but what engine is in my Camaro?
I have the V8 manual!!

[surfgun]

Yup your right! LS3 last one pictured.

[80s_Adam]

I'm really like the idea of a carb'd Ls3.

[surfgun]

I think the last Camaro with a Carb. was in 1987 305 CID. I had one with an M5. It was only rated at 150 HP.

You are correct with 1987, but my reference book rates it at 165hp. ;)

[BuellinBeef]

C'mon...someone tell me!!

You sir, have an LS3.

[BuellinBeef]

Danke!!! Thats what I thought

[surfgun]

It may have, reference materials back in the day were harder to come by. Regardless, it was not very fast, but still a fun car and my first Camaro.:thumbsup: Oh, I remember my first car only had 150 HP a 1976 Olds Cutlas with a 4-barrel 350 CID. After the 1987 Camaro, I had a 1991 RS Camaro 305 CID with a TBI rated at 180 HP or was it 190 HP?:confused:

[80s_Adam]

For '91 I have the TBI at 170hp.
