MORE POWER, WET-SUMP OILING FOR THE RACE-BRED LS7
Chevrolet Performance’s new LS427/570 builds on the trackbred 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.
CALL FOR AVAILABILITY
Each Connect & Cruise kit delivers a brand-new, fully assembled crate engine, an electronically controlled overdrive transmission, electronic control modules for both and the engine control hardware to get it all running in your project vehicle – including the mass airflow sensor, oxygen sensors and even the special throttle pedal for the engines' electronic throttle bodies.
Chevrolet Performance engineers matched the engines with their respective transmission, ensuring it was up to the task of channeling big power with absolute dependability. The engine controller is specially calibrated to run the engine without some of the production-vehicle features that aren't required in an older vehicle. That means no "trouble" codes and no need for third-party tuning. Better still, the systems' unique SuperMatic transmission controller is designed to work with the engine controller for a seamless, "plug and play" installation that is quick, easy and intuitive. Detailed instructions outline all the necessary steps.
The engineers did all the hard work of designing and calibrating perfectly matched powertrain systems – and we've covered them with a 24-month/50,000-mile limited warranty (see cheverolet.com/performance or your Chevrolet Performance retailer for complete details). All you have to do is install them and start cruising!
