please answer this quick question. (difference between ls1 and ls6?)
• Redesigned positive crankcase ventilation system improves oil flow during high speed conditions.
• Redesigned air cleaner leading to reduced restriction and greater air intake.
• Redesigned camshaft profile which allows increased valve lift, therefore more air pulled into the combustion chamber which helps to increase power.
• New intake manifold and mass air flow sensor design allows more air intake.
• Higher rate valve springs and a new cylinder head design enhance the engine's breathing characteristics for increased rpm and performance.
• New cast iron exhaust manifolds are used in place of the stamped steel manifolds which improves the flow of exhaust gases. These manifolds connect to a new lightweight, titanium exhaust system which is the first ever to be used in a mass-produced automobile. This new exhaust system incorporates titanium exhaust pipes and mufflers that contain larger louver tubes which help to reduce back pressure and increase performance.
