380DPS  On the technical side, the V8-380 features variable valve timing using a hydraulic cam phaser, plus a deep skirt cast iron cylinder block with high compression aluminum cylinder heads. It has full freshwater cooling and a high flow, catalyzed aluminum exhaust system developed for the marine enironment.The result of all this high technology is an exceptionally high power to weight ratio and low fuel consumption and emissions. On the practical side, the seawater pump, coolant reservoir and and both oil and fuel filters are located on the front of the engine for easy access. |

GM discontinued the 8.1 so this is it's replacement. Mercruiser developed their own 8.2 liter big block. The 380hp VP is the LY6 6 liter VVT V8 found in: 2007–present Chevrolet Silverado HD 2007–present GMC Sierra HD 2007–present Chevrolet Suburban 3/4 ton 2007–present GMC Yukon XL 3/4 ton Displacement: 364 cid (5967 cc) Engine Orientation: Longitudinal Compression Ratio: 9.6:1 Valve Configuration: Overhead Valves (2 valves per cylinder) Assembly Site: Romulus, Michigan Valve Lifters: Hydraulic Roller Firing Order: 1 - 8 - 7 - 2 - 6 - 5 - 4 - 3 Bore x Stroke: 101.6 X 92 mm Bore Center: 111.76 mm Bore Area: 648.59 cm2 Fuel System: Port Fuel Injection Fuel Type: Regular Unleaded Horsepower: 385 hp (287 kW) @ 5600 rpm Torque: 400 lb-ft (542 Nm) @ 4400 rpm Fuel Shutoff: 5600 rpm Engine Mass: 539 lb (245 kg) Emissions Controls: Positive Crankcase Ventilation (PCV) Materials: Block: Cast Iron Cylinder Head: Cast Aluminum Intake Manifold: Composite Main Bearing Caps: Powder Metal Crankshaft: Cast Iron with Undercut and Rolled Fillets Camshaft: Steel Connecting Rods: Forged Powder Metal Cast iron deep-skirt cylinder block with six-bolt main bearing caps that limit crankshaft flex and stiffen the 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 “selfcleaning” 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

Very nice, love the uncluttered engine bay and bilge. Is that a FW's boat the VP is in? |

Gotta love that new engine, only will GM make this fancy new V8 and throw a giant stamped steel nasty ass looking bell big f***ing pulley tumor thing on the front. Really assholes? Spend the $5 more on a $5000 engine (new automotive cost) and give us something that doesn't look like an "oh shit" afterthought. |

Good to see that marine engines are finally getting into the 21st century. That pulley looks like one that almost every other auto company has. 95% of customers will never even notice it so why spend more money? It is simple, light, strong and most likely reliable. When you start making several hundred thousand or more engines and don't need to spend $5 why do it? The money saved can be put into developing something customers will care about. |

LS motors finally making it into boats from the factory (outside of a select few wake board boats). I may have to hold off on my boat upgrade until I can get one that comes factory installed with one of these bad boys. |

The LS engine is available for boats from indmar, but for inboard only (not sterndrive). |

The LS engine is available for boats from indmar, but for inboard only (not sterndrive). Ric, you are incorrect. It is not a totally different family. The term "LS" is thrown around for any GEN III/GEN IV Chevrolet motor. The LY6 is nothing more than an LQ4 6.0L with variable valve timing and L92 heads. I could throw a set of L92 heads and an LS3 intake onto my LQ4 that is in my Camaro. The LM7 5.3L in my Avalanche, is still an LS motor as well. I can interchange any parts I want from my LQ4 and LM7, or my junk LS1 I have in the garage. Why? Because they are ALL LS motors. You can transfer the cam gear from a GEN III to a IV, pull the VVT stuff, and run whatever LS based stuff you want that works for the goals someone has in mind. Here's some reading material for you.... http://www.chevyhiperformance.com/tech/ ... ewall.html Not trying to nitpick here, but they are not a "totally different family". People have swapped these motors into everything you can think of, including boats, without paying the hefty price from a specific company. So back to my original, accurate, quote. I am glad they are finally moving away from the old school SBC/BBC and putting LS motors into boats  .

He can say what he wants, but I know a thing or two about the LS motors  . I have torn down, built, helped build, modded, etc. a few of them.

They are not "LS" engines although various parts might swap over and fit and be similar, but don't confuse them with an LS engine. Totally different heads, cranks, rods, pistons, intakes, accessories, fuel injection, virtually everything is different. Read your own article, it fully explains it. These are the only two LS engines offered for marine use, both from Indmar http://www.indmar.com/Engine/indmar/6.2lls3.aspx http://www.indmar.com/Engine/indmar/6.2 ... edlsa.aspx |

You obviously did not read the article. I know you have no experience with these motors so let me try and explain it better. Here is a quote from the article first. "Almost all the hardware amongst the different LS variants are interchangeable. In fact, except for the smallest (4.8L) and largest (7.0L) motors in the LS lineup, all share the same 3.622-inch stroke. In most instances, the cylinder heads, camshafts, crankshafts, and intake manifolds can all be mixed between different LS motors. Furthermore, while Gen III and IV truck motors are usually labeled "Vortec," they share the exact same architecture and many of the same parts as their "LS" designated counterparts." The LY6 you posted the specs to, is NOTHING MORE THAN AN LQ4 6.0L with different heads and VVT. The LS3 in the new Camaro and 08+ Corvettes uses what heads? L92's, just like your LY6. Of course the cam, accessories, intakes, etc. will be different for each application. Why would I want a truck tailored cam in a 2012 SS Camaro? My 6.0L in my Camaro, used to be in a full sized GM Van. I took the truck intake off, bolted on my LS6 intake, installed an aftermarket cam (that would work in any GEN III motor from a 4.8, 5.3. 5.7, 6.0), bolted up my Camaro's accessories, fuel rail, TB, etc. Using the factory wiring harness, computer, etc. Why? Because it's ALL interchangeable. I can bolt the L92 heads on my current motor if I wanted, would just have to get an LS3 intake since the heads have different ports. I could go to the junkyard right now, buy an LY6 motor from a newer truck, escalade, etc., convert it over to a 24X reluctor wheel, change the cam gear, front cover, cam sensor, delete the VVT, and run everything I currently have. So please, stop posting information that is not correct. Once again, the term "LS" refers to ANY GEN III/IV motor. Read the article again for clarification. |
