Now does that mean my 07 has more HP than others

Not necessarily. Here's the key passage in the Wikipedia article that you quoted:

"In 2008 SAE ratings dropped the horsepower ratings"

This could mean many things: There was a slight change between the 2007 and 2008 model year (not probable), SAE decided to remeasure using more refined criteria and found that the HP ratings weren't quite the same as they were before (pretty likely), there was a difference in the fuel mixture that day (could be), and so on...

Thinking your vehicle is superior because you might or might not have 5 extra horsepower is like thinking you have a superior, um, thingy because it is a quarter of a millimeter longer than someone else's - especially if your ruler is artificially shorter (therefore giving longer readings) than everyone else's.

Really, it's not about how much horsepower you have but whether or not you know how to use it correctly. The more critical component for getting you off the line and up to speed quickly, torque, is identical between the model years.

Check the VIN

Your earlier question gave me the impression that you wanted to know if you had more horsepower than the later models, not the earlier ones. ANYway...

I gotta get one but is there any tell tale signs on the engine that would stand out to show if it is the LZ4?? because the car is a 2007 but it was manufactured in 2006 so i'm not sure if it has the LZ4

Check the 8th character of the VIN. If it's 'N' then you have the LZ4. The model year determines the options, not the year in which it was manufactured.

You can fiddle with the year in the URL to read other VIN cards.
