Information

2020 Kodiak Marine Engines LSX 454

Features may include:

Built With Big-block Power
  • Lighter and more compact that an original Big-Block 454, the LSX is filled with a super-tough rotating assembly and features a pair of deep-breathing CNC ported cylinder heads.
  • Although the LSX 454 cylinder block shares the same basic architecture of the Gen IV iron 6.0L, there are many features added in the casting for strength and for crank case breathing.
  • The LSX 454 block has a Siamese cylinder bore configuration allowing for larger bore diameters.
  • The LSX 454 Engine is fitted with high-flow cylinder heads, based on those developed for the high performance LS3 V-8. These heads have offset rockers, like those in the LS7. Yet the LSX 454 heads maintain a compression ratio that allows these engines to operate on regular gas.
  • Fuel Injection with Stainless Steel Fuel Rail
  • Advanced Electronic Throttle Control
  • Coil Near Plug (CNP) Technology
