GM's new V6 is finally out.

the lfx being a 60 degree v6 is going to be a tall engine. the integrated exhaust manifolds have they benefits for fitment, however kills any thoughts of improving performance with a pair of headers. power specs look pretty good, and im sure there is more left in the ecm with some tuning. if i were going to do something like that id wait for the twin turbo version, this one might be a little unforgiving with boost at 11.5:1. direct injection allows for higher static compression with boost, but not that high.

im kinda torn up on the lv3. looks like an ls with 2 cylinders missing. the old 4.3l was basicly an old school 350 with 2 holes cut off, and as good as the 350 was, the 4.3l was terrible. its going to be too tall to fit with that intake manifold, and there never will be a car version to bolt to it, so a hood bump is the only option. i dunno, i think there are better options than this engine, imo, the only good reason to swap it in is it would bolt up with the current ls swap stuff, im sure the ls swap mounts would even work.
