LS376/525 Connect & Cruise with 6L80-E Transmission (3000 Stall)

This Chevy Performance LS3 is their most powerful (naturally aspirated) 6.2L LS! It features an aggressive ASA (American Speed Association) camshaft that was designed for the grueling and high-rpm world of circle track racing. Installed in this LS3, it delivers an amazing 525 horsepower. You’ll notice the new found power in both the idle quality and in the response time when revs are climbing. This powertrain package includes the engine, automatic transmission, electronic controllers and all the necessary wire harnesses – all for less than the cost of buying the components separately.

The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. And for durability, we complement the cam with higher-rate valve springs.

Chevy’s engines and transmissions are matched for optimal performance and durability, so you can push for every possible bit of horsepower with total confidence. Put this combo to work in your build and enjoy a great balance of performance and efficiency. The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation.

Chevrolet’s Connect & Cruise lineup includes several emissions-compliant E-ROD systems available in both automatic and manual transmissions. They’ve done the work to design and calibrate perfectly matched powertrain systems that are covered by a 24-month / 50,000-mile limited warranty. When it comes to performance innovations that save time, money and guesswork, Chevy crate engines and Connect-and-Cruise systems lead the way – just install, connect, and cruise.

What’s Included

The LS376/525 Connect and Cruise package comes complete with:

  • Engine (19435104)
  • Engine Control System (19354332)
  • Automatic Transmission (19417102)
  • Transmission Installation Kit (19420358)
  • Two oxygen sensors and mounting bosses (for installation in the exhaust system)
  • Mass airflow meter and mounting boss (for installation in the air intake system)
  • Throttle pedal assembly (for use with the electronically operated throttle)
  • Assembled wiring harness w/ fuse box and necessary cam and MAP sensor jumpers
  • Oil pressure sensor that is compatible with the harness
  • Instruction sheet
  • Note: Transmission controller and torque converter included with the transmission.

NOTE: All components, engine, transmission, controllers and installation kits are ordered and delivered separately.

Important Notes

For a complete installation, the builder will need to source additional components to complete the engine assembly and get the vehicle running, including:

  • Fuel tank and fuel lines (re-circulating or returnless)
  • Fuel pump – 58 psi (400 kPa) for all engines except LSA, which requires 65 psi (450 kPa)
  • Air induction system that incorporates the mass airflow sensor

Additionally, all engines require a front-end accessory drive system. The instructions included with each kit lists recommendations and Chevrolet Performance offers several configurations to suit different applications. Each allows the installer to easily delete air conditioning. Note that exhaust manifolds are NOT INCLUDED.

You’ll need tuning to make the most of this engine in a late-model GM vehicle. If you plan to use the engine in a vintage car, you’ll need LS376/525 Controller Kit P/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.

We also recommend the LS1 Engine Installation Guide P/N 88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.
