    General LS1 question about horsepower

    I am looking to buy an LS1 or LS6 for an engine swap project. I recall seeing a buch of different stock horsepower ratings for the LS1 in the past. My question is what LS1 out of what vehicle produces the most horsepower stock?

    well the LS1 is rated anywhere from 305-350hp on paper. They were made from '97-'04 They come in f-bodies, vettes, and gtos, but they all basically make the same power. An 01-04 will make a few more hp due to the LS6 manifold. The difference in the #s is mostly becuase of the intake/exhaust setups and advertising reasons. So any LS1 out of any year/type car will make similar power to that of any other.
