- LS427/570 Wet Sump 7.0L 427 C.I.D. 570 HP Crate Engine Assembly
Description:
2 IN STOCK as of 1/25/2022
Chevrolet Performance’s new LS427/570 builds on the track-bred performance of the LS7 engine and enhances it in two important ways: More power and easier installation. A new, higher-lift camshaft helps it produce 570 horsepower and 540 lb.-ft. of torque—increases of 65 hp and 70 lb.-ft. over the production-based LS7 crate engine. Additionally, a new wet-sump oiling system facilitates easier and less costly installation, because the supporting components for the production-based LS7’s dry-sump system are not required.
Product highlights:
• Based on the production LS7 crate engine
• Unique high-lift hydraulic roller camshaft with.591-in. intake/ .590-in. exhaust lift
• Unique high-rate valve springs
• F-body wet-sump oil pan and specific wet-sump oil pump
• Low-profile LS7 EFI intake manifold with fuel rails, injectors and throttle body installed
• CNC-ported cylinder heads featuring 2.2-inch titanium intake valves
• Use with LS427 Engine Controller P/N 19420000 (sold separately)
• Not intended for marine applications
