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.

Scha-wing. Damn. Wonder what the price will be?

 

Oh Joy
I can see it now-------->SDPC 427 between the shock towers of my WS6

 

why couldnt i have waited a few more months...dammit...oh well not like this motor will last forever! haha i will have an ls7 one day.

 

This makes my DAY!!!!!!!!!!!!!!!!!!!!!!!

 

My guess would be around $8000.

 

LS7 crate + cam... Count me in.

 

guess why guess today is the 22 already we can now know for sure how much it is yeaaaaaaaa.

 

That would be awsome for $8000. I was figuring closer to $15,000.

 

Didn't you read the post?

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.

 

hey what gives iam not gettign anything with that part #

 

Becasue the part number exists... but there is no quantity or warehouse location or anything yet.

 

Saving pennies... saving pennies...

 

Cool find 2kFirehawk, you da' man! Make sure everyone posts up their guess:

LS7 Crate Motor Price give-away

 

oooooooooooooo ok

 

Guys lets not get crazy thinking you are going to get this for anywhere approaching $8000.

Notice it says "Cost of comparable CUSTOM-BUILT aftermarket engines".

That doesnt just mean any 427 CI engine that means a custom built engine with all the same stuff including dry-sump and all this exotic stuff

Block: Cast aluminum with pressed-in cylinder sleeves and 6-bolt, forged steel main bearing caps
Crankshaft: Forged steel
Connecting rods: Forged titanium
Valve size (mm/in): 56 / 2.20 (titanium) intake / 41 / 1.61 (sodium-filled) exhaust

Show me a COMPARABLE COMPLETE motor (Including intake, wiring, PCM, injectors, accesories etc) to that for anywhere near $20,000 and I will be impressed.

My guess is a "comparable" motor to these are found only in race cars. Ask LG or some of the race guys on here what their dry sump motor costs then subtract a couple grand from that.

My guess

$15000 or more

 

This is probably what GM considers comparable but still doesnt have titanium valves, dry sump oiling etc:

$27000

That also doesnt include things like accesories, intake, TB, injectors, wiring etc etc etc

 

Very true.

 

1. That's installed price with 24 month warranty.

2. LPE handbuilt low volume.

I doubt it's $8000 and I'm hoping it's below $15,000. If it's near $27000 they've wasted their time on a press release.
I think Will Handzel is brighter than that.

 

Well the LS7 is going to be hand built and low volume too.

Plus GM Goodwrench engines have a 3 Year / 50,000 mile warranty so that smokes LPE's warrenty too!!

You ARE saving the install cost but that is a SMALL fraction of the cost of that motor and wouldnt even counter the fact LPE doesnt have a dry sump or titanium rods etc.
