ZZ502/502 Deluxe Connect & Cruise with 4L85-E Automatic Transmission

The ZZ502/502 is one of the industry’s benchmark crate engines and is Chevy’s most popular big-block. It offers excellent value with a proven combination of performance. With more than 500 horsepower and 580 lb.-ft. of torque, it demands your full attention. This one all-inclusive package includes the engine, automatic transmission, electronic controllers and all the necessary wire harnesses – all combined for less than the cost of buying the components separately.

Thanks to a combination of high-flow aluminum oval-port cylinder heads with 2.25/1.88-inch valves and a hydraulic roller camshaft designed to support low-rpm torque production, this torque monster tops the 500 lb.-ft. mark by approximately 2,500 rpm and doesn’t dip below it until about 5,000 rpm. It also features a latest-generation block casting with four-bolt main caps and an all-forged rotating assembly for exceptional strength and durability.

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 classic cruiser 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 and for operation without the need for 3rd party tuning. The Deluxe package comes complete from the oil pan to the carburetor, including an HEI distributor, plug wires, starter, water pump, balancer and an aluminum intake topped with a Holley 870-cfm four-barrel carburetor.

Chevrolet’s Connect & Cruise lineup includes several emissions-compliant E-ROD systems available in both automatic and manual. Each system is designed and calibrated to perfectly match the engine powertrain systems and is 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 start cruising.

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, this engine requires 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.

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.
