Previously equipped in vehicles like the 2014 Chevrolet Camaro Z/28 and C6-generation Chevrolet Corvette Z06, the naturally aspirated 7.0L V8 LS7 is well-known for its big output numbers and smooth power delivery. Now, Chevrolet Performance has unveiled the new-and-improved LS7-based LS427/570 crate motor with even more performance on tap.
Chevrolet Performance frames the new crate motor as “an enhanced version of the production-based LS7 7.0L engine that offers more horsepower, more torque and, thanks to a simpler wet-sump oiling system, easier installation.”
Output from the new atmospheric ‘eight is rated at 570 horsepower and 540 pound-feet of torque. For those of you keeping score at home, that’s an increase of 65 horsepower and 70 pound-feet of torque compared to the standard production engine, making the LS427/570 the most powerful naturally aspirated LS crate engine on offer.
The new crate motor also gets a new wet-sump oiling system, which means it doesn’t need a separate oil tank, lines, or any of the supporting components from the standard LS7 dry-sump system.
According to Chevrolet Performance, standout features include a new high-lift camshaft that was developed specifically for this particular application, as well as titanium intake valves and sodium-filled exhaust valves. The connecting rods are also made from titanium, while the crankshaft is forged steel. The cylinder heads were CNC-ported as well.
Final touches include a low-profile LS7 EDI intake manifold, fifth-generation Camaro Z/28 exhaust manifolds, and a 14-inch Camaro Z/28 manual transmission flywheel.
Chevrolet Performance says the engine requires the LS427/570 Engine Controller P/N 19420000, which is sold separately. Mobil 1 15W50 fully synthetic motor oil is recommended.
The new 570-horsepower crate motor is available to oder now through Chevrolet Performance dealers and retailers. We should also mention that this engine is designed exclusively for competition vehicles, and is not intended for use on public streets or highways.
At a time of year when luxury car ATP usually rises.
Sales decreased 5.6 percent to 16,670 units during the first ten months of 2024.
Specifically critical minerals supply chain development.
Scheduled for a Spring 2025 launch.

Oh the things I could achieve if I had half the smarts some of you gentleman and ladies seem to have just by reading some of your comments. But honestly enough with the muscle cars get back to the real soul of Chevrolet and General Motors *Trucks* not dissing the cars by any means just wanna see more effort towards the 4x4's which sadly seem to be going down hill since... well... plastic riveted fender flares became an option! 😭😝 But congratulations GM on your newest motor achievements none the less it's impressive!
Have a 408" LS3 with quality forged internals on the engine stand I just built, and betting it will easily match those horsepower numbers for far less money. And be very street friendly.
I have a 2001 Corvette that I would like to put an LS 7 into. What all would I need to get that done and not upset the computer system in the car?
What?! Are you even serious?? If you don't know ANYTHING about a swap, DON"T DO IT! FYI, an LS7 was not put into a Vette until Gen 6 and had a TOTALLY different ECU. OMG, I don't even I replied to this....Fook Me.
That is a popular swap, so there are kits that do this. You'd need an ECU adapter and possibly (probably) a new transmission.
Best to have an experienced shop do it.
Convert to cable throttle, get some cable extension for cam and crank sensors, swap on some headers. They can pull the tune of the computer if you wanted to keep it simple, convert it to work with the stock computer and then tune it. T56 Transmission can take the power but will need a new clutch. Don't forget to convert the fuel lines to return-style.
Little more involved than that but you can start and complete most of the work in a weekend.
would this be a swap out for the ls7 in a 2008 Z06 that's dropped a valve and popped the motor
No because your ls7 was dry sump. Put this in there the oil pan will hit everything.
I would love to put that in my base C6 convertible
