GM Performance Parts is unveiling the crate engine version of the LS7 engine that powers the 2006 Corvette ZO6. This latest Z06, billed as "the fastest, most powerful car ever offered by Chevrolet and GM," has enthusiasts looking for that kind of power in a crate engine. GM Performance Parts is ready to end that search as it offers the LS7 (P/N 17802397) at GM dealerships and Authorized Centers nationwide in August.

Pricing has not yet been announced

thats awesome. i still think the old L88 427 was most powerfull, as its said to be underated about by 100hp or so which makes it over 500hp but this new LS7 is gonna rock!

i am so excited to see it go, and i cant imagine this motor will be cheap. probly 9 grand at least, as it has titanium rods and forged bottom end, unless they change that for the crate motor

Thats great and the horsepower is awesome but what type of fuel management and computer system will it need. Thats got to be another thousand or so on top of the 12,000 crate motor price. Does it come with the motor? Anyone know?

At least as good as the L88 was the ZL1. An all aluminum 427. I remember seeing one at a dealer in Colorado. IIRC, the sticker for that Camaro was $7200 (keep in mind that this was 1969). Wish I could have afforded it. Looks incredibly cheap now.

The ZL-1 was even more extreme than the L-88 was. It was basically the same engine, but with a bigger cam, aluminum block, and *i think* factory headers. The L-88 did have aluminum heads the same as the ZL-1, but an iron block, tamer cam (its all relative here, lol) and cast iron manifolds the same as the other regular 427s had. They both had MASSIVE solid lifter cams (though they used different cams), 12.5:1 CR, alm heads, 850cfm Holley 4bbl, and all the heavy duty driveline and cooling parts. Both engines still had severe cooling issues, in either the Corvette or Camaro chassis. The Camaro never got the L-88 btw.

Well, I'll be damned..

Most Powerful Small-Block Ever - Available in a Crate

DETROIT - Chevrolet unveiled the 2006 Corvette Z06 at Detroit's North American International Auto Show in January, and now GM Performance Parts is unveiling the crate engine version of the LS7 engine that powers it. This latest Z06, billed as "the fastest, most powerful car ever offered by Chevrolet and GM," has enthusiasts looking for that kind of power in a crate engine. GM Performance Parts is ready to end that search as it offers the LS7 (P/N 17802397) at GM dealerships and Authorized Centers, nationwide in August.

This small-block V-8 dreams big, displacing big-block cubic inches at 7.0 Liters (427 cubic inches) and big-block power at 500 hp at 6200 rpm. It also benches 475 lb.-ft. of torque at 4800 rpm. Helping to create its high power and high revving capability are details such as cylinder heads with computer numerical control (CNC) intake and exhaust ports and combustion chambers - which creates ports with surgical accuracy for maximum power production. In addition, the intake valves and connecting rods are made out of high-strength lightweight titanium.

The LS7 engines are assembled by hand at GM Powertrain's new Performance Build Center in Wixom, Mich.

Pricing will be announced mid-summer; however, early estimates indicate that the GMPP LS7 crate engine will sell for well below the cost of comparable custom-built aftermarket engines.

Enthusiasts who must have the latest technology, maximum horsepower and the largest production cubic-inch displacement small-block ever built will be able to purchase the LS7, as well as other GM Performance Parts crate engines, blocks, heads and components, from GM dealerships or GMPP Authorized Centers nationwide. Following the release of the LS7 in a crate, GMPP will offer select parts, such as the crankshaft, connecting rods, cylinder heads and valves separately, and in kit form. To locate the closest GM dealership or GMPP Authorized Center or dealership, call 1-800-GM USE US or visit www.goodwrench.com.

My guess? $7-10K

It is going to be much higher than that.


Chances are it will come with an ECM and wiring harness. The only part of me that hesitates to say that is based on the fact that the LS2 crate does not come with said parts. None the less, for the price you will be paying for this motor another grand for the wiring and ECM should be pocket cash. This motor will be between $12k and $15k if not higher.

Doesn't GM's latest ZL-1 (the all aluminum 454) go for $16,000 to $20,000? I don't know how they are selling (a dealer in Santa Ana has had one sitting in the parts department for months), but the new 427 should be up around there.

Edit: For about $17,000 with tax (maybe a little more, I'm doing this off the top of my head), you too can be the proud owner of GM's latest all-aluminum 454 big block. See Leonel at Guaranty Chevrolet in Santa Ana.

As for that 427?

Fasten your money belts, ladies and gentlemen, this is gonna hurt real bad.

yeah i kinda forgot about the ZL1 but maybe i was thinkin of it

Ls6 454 was also powerful too from GM but not in a vette till 71 and then detuned a bit, but alot of "experts" believe the L88 was over the 550hp mark! dang

anyway, ls2 crate is about same price as LS1 about 5500bucks or so. electronics i am not sure if it came with them as SDPC didnt mention it, so i assume its not with it....

LS6 is 7500bucks and not even as potent as the Ls7

now that i think about it, 10K + is a good estimate, if it is the same as the production Z06 motor with all the goodies inside of it. LOL thats one of the stoutest motors ever built, on par with the Supra and 03-04 cobra's

I hope I am, but I doubt it until I see it. Do you have some sort of top secret info that has spilled the price in your lap?

Drastius

I'm sure it is the most powerful production engine ever from GM.
A lot of those old horsepower numbers cannot be trusted, they are usually lower than their rating.

f-crazy

iTrader: (-1)

well something like that...my uncle heads the Engine assembly facility in Wixom MI, and when i was there when they started building the "first production batch" as he called it, he told me that as long as everything goes as planned it will be under 10k....didnt give an exact price though..im guessing he couldnt give that out....

Orr89RocZ

iTrader: (20)

well the LS6 is just under 7500, so i assume the LS7 to be 9500 or so IF it is to be priced under 10grand

Considering the upgrades over an LS6, if it sells that cheap it will be a bargain!
I remember when the original LS-6 and LS-7 crate engines were advertised in all the magazines, like 15+ years ago, for around $2700.
