Chevrolet 6.0L Vortec V8 VVT Kodiak Marine Engine (LY6) FEATURES

Factory-installed EFI hardware, including coil-near-plug ignition, is standard on the Vortec 6.0L GEN-IV Kodiak marine engine.

  • Cast iron deep-skirt cylinder block with six-bolt main bearing caps that limit crankshaft flex and stiffen the marine engine’s structure
  • Cast aluminum structural oil pan for additional rigidity
  • High-flow aluminum cylinder head design
  • Variable valve timing using a hydraulic cam phaser* to retard cam timing for low end torque and advance cam timing for high rpm horsepower
  • Steel camshaft, hydraulic roller lifters, and steel roller rocker arms for reduced friction and excellent durability
  • Returnless fuel injection with stainless steel fuel rail
  • Electronic Throttle Body fully compatible with electronic throttle control software in the MEFI-5 engine control module
  • Coil-near-plug ignition system with 58X crankshaft position encoder, 4X cam sensor, and dual flat response knock sensors for precise control of ignition timing under all operating conditions
  • Iridium tip long-life spark plugs with improved “self-cleaning” properties which decrease the potential for plug fouling
  • External water crossover integrated into the water pump casting so that no coolant flows through the composite intake manifold
  • Inconnel (high temperature) exhaust valves for long-term durability
  • Revised cam phaser for improved idle quality
  • Shallow sump oil pan for marine applications
  • Floating pin pistons which reduce noise and increase durability
  • Heavy-duty timing chain with a new leaf spring dampener to ensure quiet operation and long-term durability
  • New oil pressure sensor (more robust) – no impact on mating connector/pinout/cal – black insulator
  • Reduced hex height spark plugs – lower boot insertion force, no change in functionality – mid-year change
  • Sil-1 nitrided intake valve added (for future E85 capability)
  • Block and camshaft revisions to accept Al-Sn (Pb-free) cam bearings
  • Brico 3010 intake/exhaust seat inserts (E85 capability)
  • LS9 timing chain tensioner (improved durability)

*Camshaft Phasing: the L96 features variable valve timing, maximizing engine performance for given demands and conditions. At idle, for example, the cam is at the full advanced position, allowing exceptionally smooth idling. Under other conditions, the phaser adjusts to deliver optimal valve timing for performance, drivability and fuel economy. At high RPMs, it may retard timing to maximize airflow through the engine and increase horsepower. At low RPMs, it can advance timing to increase torque. Under light loads, it can retard timing at all engine speeds to improve fuel economy.
