Could have potential for a track car.

General Motors is showing off a new 6.2-liter toy at this year’s SEMA show, and it’s not a concept. Yes, consumers will actually be able to purchase the LS376/525 crate engine, which comes from the factory with 525 horsepower at 6,300 rpm and 489 lb.-ft. of torque at 4,400 rpm. The engine is designated as part number 19259233 and carries a suggested retail price of $8,937.50.

Using the LS3 production engine – the same used in Corvettes and Camaros – as the foundation for the LS376/525 helped keep the retail price lower, while the ASA camshaft is a proven, power-building component that has been successful in the high-rpm world of circle track racing.
The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breath exceptionally well at high rpm. Chevrolet Performance complements this high-performance camshaft in the engine with higher-rate valve springs.

I like that part...

Wonder if you will be able to get the ASA (I'm assuming GMPP also) camshaft installed on a Camaro LS3 with all necessary parts needed (springs, etc...)

Part # 12480110
ASA Cam

I: 226 E: 236
I: .525 E: .525
110
Cam requires valve spring P/N 12586484; 'ASA' cam for off-highway use.
MSRP $459.60

I think you'll find the 525 hp rating is calculated differently than "as installed Net HP" as per RPO-equipped...

Believe me, this engine with this cam, will NOT outpower an LS7...

A word about "crate" engines...and marketing...

19201992 - LS3 = 430hp (204*/211*, .551"/.522")
12594727 - LS376 = 480 hp (SAME Heads/Pistons, 219*/228* .525"/.525")
19259233 - LS376 = 525 hp (L92 Heads, 226*/236* .525"/.525")

Slightly different, non-CNC'd heads and a longer duration-but-lower lift cam = 95 hp? Over a base Corvette LS3?

Really?

That would be a cam and a set of L92 heads that will net you the 525 hp from the 6.2 LS3 ASA 376/525 package but the cam alone 376/485 package has a slightly more street friendly idle. I wonder which would be easier to certify for the 6.2 LS3's horse power swan song...... like the LT1 was to the LT4..... and like the LS1 was to the LS6.... we need a final bearer from the genIV for the 1LE or Z/28 boss killer.

P.S. I would take an assembly line built 7.0 LS3 if it was to save some money if that is more reasonable for the Camaro without the some of the expensive Z06 parts, just a suggestion, call it an LS5.

With that lift and the only 110 LSA it's gonna have a lot of lope. Probably more than a lot of people would like.

Wow!!! That's...WOW

The question before asking for it in a production car...is its emissions output...

Still - WOW!!!

That cam is not going to be able to pass emissions to much overlap and tight lobe separation, that's why it is a off road package. But here is a thought, back in the day my dad told me about the dealer saying they could switch his cam in his chevelle to a 427/425 cam. Maybe dealers will become more passionate about cars like back in the day and start offering customers these sort of options. Like let's say a LS9 cam upgrade for the LSA.

Is this the same engine as what they showed in the SSX last year?

I would say pretty close with the SSx using dry sump oiling.

The SSX, being a year-ago teaser, probably had a similarly-modified engine, but NOT likely this specific cam... IIRC, no specific HP figures were disclosed.


2011 CHEVROLET CAMARO SSX TRACK CAR CONCEPT

Ever since the new Chevrolet Camaro's launch last year, owners have explored the performance potential of the car. The Camaro SSX Track Car is a concept for transforming a street Camaro SS into a closed-course track car, and a showcase for new performance parts.

"The SSX concept explores taking Camaro's excellent street performance and extending it into a road course context," said Chris Perry, vice president, Chevrolet marketing. "The car expresses Camaro performance while also signaling Chevrolet's new commitment to developing and offering a portfolio of performance parts for racing enthusiasts."

The Camaro SSX Track Car has a purposeful aesthetic, with exterior appointments and suspension modifications aimed at road course performance. They include carbon fiber aero parts – front splitter and adjustable rear wing – lightweight carbon fiber body panels, revised lower grille and unique brake cooling ducts. The carbon body panels significantly lower the Camaro's weight, as does the elimination of much of the production car's sound-deadening material, carpeting and rear seat.

Low-gloss Icy White Metallic exterior paint is contrasted with the carbon aero parts, door graphics/racing number and red details; and this competition-ready Camaro rolls on dedicated track wheels and tires. This concept was constructed with input from Pratt and Miller, Chevrolet partner in Corvette Racing, and Riley Technologies using parts proven in the Grand Am racing series.

VEHICLE HIGHLIGHTS
Exterior:
• Icy White Metallic color with red accents and door graphics
• Carbon fiber hood, fenders, door and deck lid
• Exposed carbon fiber front splitter, rockers and adjustable rear wing
• Unique lower grille and brake ducts
Interior:
• Carpeting, sound deadener and rear seat deleted
• Ace suede-covered racing steering wheel and shifter
• SCCA-approved roll cage and window net
• Racing driver's seat with five-point harness
• Racing pedals
• Fire suppression system
• Fuel cell
• Video camera system mounted on the roll cage
Performance:
LS3 6.2L V-8 enhanced with Chevrolet Performance Parts' camshaft, cylinder heads and dry-sump oiling system
• Production six-speed manual transmission with Corvette ZR1 twin-disc clutch
• Low-restriction air induction and exhaust systems
• Four-wheel disc racing brake system with six-piston front/four-piston rear calipers and drilled and slotted rotors
• Modified production suspension with Pfadt licensed components
• 20-inch racing wheels and tires

Iam intrested in this cam, it might make for a pretty nasty street car with bolt-ons! Nasty sound and good torque so the 480hp is the ls3 with just this cam, so mabey with headers and intake your looking at a 520-530hp ls3! I would love to see this cam tested.

Again, folks, these "power" ratings are NOT "as-installed in a Camaro", and that's where some of their "optimism" comes from...

Getting 100 honest net extra hp from a relatively mild cam (.525" lift) and non-CNC'd heads (L92's are NOT the be-all and end-all of LS cylinder heads!), "as installed" with exhaust (regardless of whose you have) and emissions compliance and a streetable tune is a very TALL order to deliver... Remember, ASA runs "spec" fuel, NOT the stuff you'll find in CA., where emissions and tune are two words you can't avoid.

For liability's sake, as well as day-to-day practicalities, GMPP states "for off-highway usage"...

I repeat, this is NOT a street-legal alternative to an LS7 for us...

A hell of a choice for your "non-emissions necessary" hotrod, though!

Slightly (italix'd for a reason) better flow numbers...but NOT equal to LS7 heads...

The 110* guarantees a great "drive-in" lope...badass, to use a popular phrase...but hell for vacuum for your power brakes!
