Summit Racing’s Project 1000: A 1,000 Horsepower 6.0L LS Engine Build (Part 2, Top End & Dyno Run)

In Part 1, we introduced you to Project 1000, a 6.0L Stroker 408 engine based on a Chevy Performance cast iron LS engine block. Our goal is to build a LS motor that’ll deliver 1,000 rear-wheel horsepower, and we’re using off-the-shelf parts right from the Summit Racing website to do it.

While that first video showcased much of the engine’s bottom end and rotating assembly, now we’re going up top to show you Project 1000’s cylinder heads, ignition, EFI system, and perhaps most importantly, its twin turbo setup.

Then we take our Project 1000 LS high performance build to the engine dyno for some tuning and to see if we hit our horsepower goal. And we’ll show you the results, dyno chart and all. Then, we’ll recap the whole build and share what we learned along the way.

Want to build an engine like this too? Here are some of the key parts used in the video:
• Chevrolet Performance 6.0L Gen III Cast Iron Engine Block:

• Trick Flow GenX 220 Cylinder Heads for GM LS2:

• Holley Aluminum LS Valve Covers:

• Summit Racing Valve Cover Gaskets:

• Delphi Camshaft Position Sensor:

• ICT Billet Camshaft Position Sensor Delete Plug:

• Summit Racing High-Output Ignition Coils:

• Summit Racing Ceramic Ignition Wire Set:

• Summit Racing Fabricated Intake Manifold:

• Holley Dominator EFI Vehicle Management System:

• DeatschWerks Fuel Injectors:

• VS Racing Turbochargers:

TOOLS USED IN THIS VIDEO:
• COMP Cams Hi-Tech Pushrod Length Checker:

• Digital Caliper:

• Valve Lash Adjusting Wrench:

• Torque Wrench:

I almost done with my 408 stroker. I’m using a lot of y’all’s parts. It has a forged rotating assembly, clevite h series bearings, melling 10295 oil pump, y’all’s 8722R1 cam, btr springs, yella terra rockers, hardened push rods, ported 317’s, Hinson c5r timing chain, billet sprockets, 7 quart pan, Holley hi ram, 88mm turbo, Bosch 220’s 10an line, motion raceworks flex fuel sensor, gmpp 3 bar map, arp top to bottom, 50mm waste gate and bov, 4l80e with tci triple disc, hd2 shift kit with boost valve and servo… I still have quite a bit to add to it before it’s all done and drivable. I have a 1000whp on E. Y’all make building a LS easy as can be ESPECIALLY living close to Arlington!

Wow😮, I would like that in my 2009 Silverado. I wouldn't have any problem with pulling my Mako boat to the coast. Oh yeah, I am still running the original 5.3 with over 250, 000 miles, and no problems with it. I've only replaced number one coil, that's all I've done to that engine!

[zelly]

Just would like to say thanks for the build why some are not happy with it I’m sure it’s helping more people out so continue to do these builds

[colerussell]

Absolutely love how you guys put the part numbers in the video!!

[danielneff]

Nice Build!
How much does everything cost for the materials used on this?

[rightsidelanechoice]

To make sure your intake valve is on base circle the best way is to put the push rod on the exhaust lobe of the same cyl. When the pushrod begins to open the intake is on base circle.

I went with a single turbo my build gen4 block 413 with 98mm turbo I'm using a turbosmart eboost 2 controller i can have 6 maps for e85 and 98 around town I got all my Aeromotive fuel system from summit and was painless getting it all sent to Australia as I couldn't get anything local that could handle my fuel needs nice to know I can get stuff sent from the USA to Oz without hassles

A better exhaust manifold and a slightly smaller turbo that still makes at least 1000hp but wakes up earlier would be something that i'd prefer for a "street" engine. Doesn't even need to be a 6.0 liter, a shorter stroke paired with a longer connecting rod would be nice for wear and tear especially with a 2618 alloy piston.

[michaelandersen]

How long do you expect this combination to last?

[CBiskitone]

I just purchased a Chevy Caprice PPV with the L77 in it. Will these parts work with it and a supercharger?

[ThatGuyFromTexas]

On push red rod checkers I find nylon tape helps keep them in place

[cloudrehzii]

Would love to see the same build but with specs for a pro charger etc

[grangortransamws]

Is there a reason why you don't ceramic coat the I take to reflect hat away and maybe keep a few degrees cooler for the intake air?

[chrisbueschel]

did you say 14 degrees of timing? wow plenty left in that motor!

[DicePerformance]

When finding the right pushrod length, why did you add the .070 to it and how did you come up with that number ? But awesome work !

[adamdiaz]

Have u guys got a full list of what was used to build I’m very intrested

[patrickwendling]

Thank you for your knowledge and video's USA 🇺🇸 USA 🇺🇸 USA parts ONLY

[roderickdixon]

What type of transmission would be required for this build nd I kno it's going to be built

[Vuhjayjay]

Are you guys going to do a run down on price per part and overall cost

[superior]

Summit I want to buy the 5.3 450hp 420 torque lm7 engine. Question is should I buy that one or a 6.0 . I want N/A power for now and then turbo it after. For a 2000 Chevy Tahoe 2wd. It's something different but I'm doing it.
