ls marine engine
We wanted less power density. At 14 liters, the engine is basically two LS7s mated together, so the 4.125-inch bore and 4.000-inch stroke dimensions remain.
System engineered to work with Fluidamper balancer #212-620121, This system has an included closed cooling tank that MUST BE USED. The foundation for this 14-liter marine powerplant is a patent-pending M16 cylinder block that supports four production-style LS3 or LS7 cylinder heads along with separate conventional intake manifolds. Performance figures on headers vary considerably. header systems share 100% 316L stainless steel construction. The GM LS 1,2,3, and 6 series engines can use these Solid Works/CAD engineered engine mounting brackets. “To do a V16 automatically requires a block. “We have lower instantaneous acceleration on the crank because we’re firing every 45 degrees [of crankshaft rotation], so the harmonics are very much in line with a production engine,” he says. These engine mounts are perfect for the boater that wants to make the switch to modern efficient engines. Not for use with engines using a camshaft with more than .226 @ .050 Camshaft Duration. The current engine design includes dry-sump oiling, using a 6-stage pump. “It’s a single block but we have a gap in the middle that allows us to put on the V8 heads,” explains Caleb Newman of Performance Design, which handled the project’s engineering. *Camshaft Phasing: the L96 features variable valve timing, maximizing engine performance for given demands and conditions. The foundation for this 14-liter marine powerplant is a patent-pending M16 cylinder block that supports four production-style LS3 or LS7 cylinder heads along with separate conventional intake manifolds. If you are one of thousands of performance boaters oseeking the power and styling from stainless The GM LS based engine family has already dominated the automotive industry and has quickly become the high performance standard in the performance boating world.
