LS1 and LS6
LS1 and LS6 Could somebody post all the specs for the LS1 and the LS6? Why the F-bod LS1 is different then the C5 LS1, and could someone explain why the 25% of the 2002 F-bods that got the LS6 have no performance advantage?

The difference from LS1 engine to LS6
• Redesigned engine block includes quarter size slots cast into the webs underneath the travel area of the piston which reduces the amount of air the pistons pump resulting in higher rpm output.
• 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.

So basically the only difference that applies to the f-bodies (and GTO's which all have LS6 blocks, btw) is the second item? No performance gains by using the block, but better oil flow at performance speeds allowing better reliability?
