What does it mean to be unresponsive? What's the difference between unresponsive and unconscious?

In chev. engines, what exactly does LT1, LS1 mean? Is there a 'collectors edition' corvette engine around the years 2000-2003? Whats the difference between 350ci. and 350hp?

• Answer:

  The LT-1 is a 2nd-gen small-block made from '92-97. The LS-1 is a 3rd-gen small-block made from '97-present. The technical differences are too numerous to list. The Corvette Z-06 ('01-04) used the LS-6, a modified LS-1. The 350 CI refers to displacement, a measure of how much air the engine moves in one complete cycle (two revolutions of the crank), which is 350 cubic inches or about 5.7 liters. The 350 HP means that it has a peak output of 350 horsepower (~260 kilowatts) at the crankshaft. All else being equal, a larger displacement engine will put out more horsepower BUT ALL ELSE IS NOT EQUAL! Despite what some people will tell you, there are a number of 2.0 liter engines that will outperform 5.0 liter engines without resorting to turbos or such merely because all else is not equal. Using displacement to estimate power output only works amongst engines of similar design; that is "from the same manufacturer". Once you go from one maker to another, there are enough differences that a direct comparison is effectively impossible based on displacement alone.
