That's more like it, a few lt1 guys are willing to publicly admit they're not slow.

Stock for stock, yeah, the ls1 wins. I think the point could be argued, but the ls1 probably has more ultimate potential, through more efficient design and even if only because the ls engines are the new standard and will be for the forseeable future. I was thinking along the lines of formula69, that comparing a heads/cam lt1 ("done right", of course) to a heads/cam ls1, the power difference is not large enough to discount the lt1 considering the large premium you pay to get into an ls1 car. It's like the lt1 is the unwanted Chinese daughter of the GM world.

Good discussion on the topic, and good points on an argument going through my head as I worked helping my friend swap an engine into his lt1 firebird today.
