Chevy Announces the 570 HP, Racing-Bred LS427/570 Crate Engine

The all-new LS427/570 7.0-liter crate engine aims to give builders more power and less hassle. A new wet-sump oil system as well as a raft of speed parts makes this an even better choice for your build.

There are increases in power, but the thing that’s really going to make your life easier is the wet-sump oil system. That makes installation easier, says Chevy, because you won’t have to plumb in your own separate oil tank, oil lines, and ancillary components like you do with the LS7’s dry-sump system.

A new high-lift camshaft that Chevy Performance developed specifically for this application (as well as some more improvements listed below), means that the crate engine also gets 65 more horses and 70 more lb-ft of torque than the LS7 for a total 570 hp and 540 lb-ft of torque.

“The all-new LS427/570 builds on the legendary, racing-bred performance of the LS7 to create the most powerful naturally-aspirated LS crate engine in our portfolio,” said Jessica Earl, GM specialist marketing group manager, in a statement.

The LS427/570 also comes with an F-body aluminum oil pan as well as the following improvements:

  • Unique high-lift hydraulic roller camshaft with 0.591-inch intake/0.590-inch exhaust lift; 227-degree intake/242-degree exhaust duration; and a lobe separation angle of 116 degrees
  • Unique high-rate valve springs
  • Camaro fifth-generation Z/28 exhaust manifolds
  • Low-profile LS7 EFI intake manifold with fuel rails, injectors and throttle body installed
  • Robust LS7 rotating assembly featuring a forged steel crankshaft and titanium connecting rods
  • CNC-ported cylinder heads featuring 2.20-inch titanium intake valves and 1.61-inch sodium-filled exhaust valves
  • Fourteen-inch Camaro Z/28 168-tooth manual transmission flywheel
  • Must be used with LS427/570 Engine Controller P/N 19420000 (sold separately)
  • Chevrolet Performance recommends Mobil 1 15W50 fully synthetic motor oil to be used with the engine

You can order the engine right now from Chevy Performance’s website.
