Could have potential for a track car.

Ok I'm listening...any details???

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.

1LE plus this

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...)

LOWDOWN · 11-03-2011, 05:32 PM

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?

Yeah, 100HP just from a cam???

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.

Isn't the 525 hp version for carbs?

EDIT"
My bad. this is a new version.

PQ · 11-03-2011, 08:39 PM

9k and no ECU........

Big cam, and think about some FI.......

b4z · 11-03-2011, 08:55 PM

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.

2cnd chance · 11-03-2011, 10:12 PM

That would be awesome!
