Will the long awaited return of the Camaro be a hit?

Big-time muscle

I've always been a Ford guy, but that is definitely a Chevy that I'd be VERY proud to drive around!!!

I'm hearing they will be powered by the LS2. Performance with economy, in an
attractive RWD chassis the prefect combination.

the LS3 is more likley (6.2l) with displacment on demand , variable cam timing, and possibly other gysmos for increasing fuel milage. still lots of tuning potential tho i think we are long past the dark emission control days of the 70's when muscle turned to jelly with an all time low SBC output of 110HP out of 262 cu in in 1975 (yuk).
the modern idea that if you increase the efficiency of the engine its emmissions go down is good for tuners, as they are fitting bigger valves and throttle bodies, and better intakes which leaves lots of power on the table for those who want to gofast.

If only I had the money...

But I can't wait until these come out.

Oilman, do you have more information in the LS3? I'm interested in bore
size and cylinder head design.

Consumer Guide's Impression of the 2008 Chevrolet Camaro:

With nostalgia-exploiting styling and a promise of 400 horsepower, the 2009
Chevrolet Camaro has good looks and muscle to match. But by its 2009
launch date, will anyone still have Camaro fever?

Chevrolet Camaro Prices: Expect Camaro coupes to start around $25,000 with
the V-6, with top-of-the-line V-8 convertible versions breaking $40,000 fully
equipped.

Chevrolet Camaro Release Date: The Camaro coupe is scheduled in
showrooms in spring 2009. The convertible version, a 2010 model, could be
on sale about a year later.





2009 Chevrolet Camaro Review and Prices

Bore= 103.3 mm

Cylinder head design taken from LS7

Chevrolet probably will not provide the full 436 HP of the 2008 LS3 Corvette in the Camaro.

Thanks Cammer,
I got tired of waiting for GM to roll the new Camaro off the production line. I
started collecting parts to build my own version based on this worn out 69
Camaro. I was able to pick up a low mileage LS2 from a Katrina flood Corvette.
I'm looking to upgrade the heads, it sounds like the LS3 version is just what I'm
looking for.

Take plenty of photos and keep us informed on Camaro project progress.

You will love the LS2 in your Camaro.

The new GM engine designs are perhaps the finest in their history.

Best of luck with your project!

Thanks,I will take plenty pictures. The information in the last paragraph sparks my interest.

I found this on the 2008 Corvette engine:

This new iteration of the storied small-block family features a
revised,larger-bore cylinder block - 4.06-inch / 103.25 mm vs. the
previous 6.0L's 4.00-inch / 101.62 mm bores - high-flow, LS7/L92-style
cylinder heads; larger-diameter pistons; revised camshaft and camshaft
timing;revised valve train with offset intake rocker arms; high-flow intake
manifold; high-flow fuel injectors from the Z06's LS7 engine; and a new
engine beauty cover.

The LS3 features an aluminum cylinder block with cast iron cylinder liners.
In addition to its larger bores, which help create a 376-cubic-inch
displacement, the block casting also features revisions and machining in
the bulkheads that enhance its strength and improved bay to bay breathing.
But while the bore of the 6.2L engine is increased when compared with the
previous 6.0L engine, the engine's stroke remains at 3.62 inches (92 mm).
The pistons for the larger 6.2L engine also are new and are designed for its
high-rpm performance capability.

Breathing for the new 6.2L engine is accomplished via new, high-flow cylinder
heads. They're based on the large port/large valve design found on the LS7
engine and other GM L92 engines, with larger-capacity,straighter intake ports.
The design optimizes intake flow to the combustion chamber and the exhaust
ports are also designed for better flow. Complementing the larger-port design
of the heads are commensurately sized valves. The intake valve size alone
increases from 2.00 inches(50.8 mm) to 2.16 inches (55 mm) - an increase
of nearly 9 percent. The intake valves feature lightweight hollow stems, which
enable the engine's 6,600-rpm capability. The exhaust valves also are large,
measuring 1.60 inches (40.4 mm) in diameter.
