Crate motors are complete packages that allow retrofitters or converters to equip an existing chassis with a new drive. Now, Chevrolet Performance has introduced an all-new LS427/570 crate engine to replace low-performance base engines. The new engine offers more horsepower, more torque, and, thanks to a simpler wet-sump oiling system, easier installation.
A 7.0-liter 570-horsepower V8 engine is an enhanced version of the production-based LS7 7.0L engine. The latter was found in the Corvette C6 generation sports coupe in the more powerful version of the Z06, as well as the Chevy Camaro Z/28. As representatives of the automaker assure, thanks to a large number of various upgrades, the new Chevy LS427/570 has more performance than its predecessors.
To improve the existing LS7 engine, GM engineers added a new camshaft, valve springs, forged crankshafts, titanium connecting rods, and a low-profile intake manifold to its design. Thanks to this, it was possible to increase the output of the eight-cylinder engine by 65 hp and 95 Nm.
Among the advantages of the new generation of Chevy crate engine, a wet sump lubrication system is noted, which eliminates the need to install a separate oil tank, oil lines, and other auxiliary components for the LS7 dry sump production system. For the engine, the retrofitter still needs a specially tailored engine control module. Manual gearboxes must be able to dock onto the flywheel from a Camaro Z/28.
The crate engine is capable of spinning up to 7000 rpm. According to General Motors, this is their most powerful atmospheric engine. It is noteworthy that the LS427/570 cannot be legally installed in a road car (in any case, in the USA). The motor is designed for racing and other projects, so the path to public roads is closed to it.
The American automaker will sell this engine fully assembled – with all the necessary components and assemblies. GM has not yet announced a price for the new Chevrolet LS427/570. I must say that the possibility of acquiring such “ready-made” solutions is a dream for many really cool tuning projects.
