I don't understand the reuse of the LT platform designation but it is freakin cool nonetheless!

The YT shows a different design on the water pump, I wonder why they did that.

I don't know why they used the LT designation so soon either but I could careless what it's called as long as it hauls ass.
Only thing I hated about the press conference was how they said they hope the computer code is hard to crack. Bad news for BBP.

I didn't even know they had a press conference, is it on YouTube?

I don't know if it was an official press conference but they released the info to the public.

I'm hoping those numbers conservative. I loved the Gen III/IV "LS" but so far I'm underwhelmed with what I just read on the Gen V "LT". A ground up redesign, direct injection, and a "radically new combustion system" but horsepower only went up 20 while keeping the same displacement? Not that 450hp is anything to scoff at, it just doesn't seem like the generational leap that was expected with the addition of all those fancy new technologies. An LS3 could probably hit 450 very easily. Also disappointed they kept the practically useless single-cam VVT just for the VVT badge, was hoping for a cam-in-cam similar to ChryCo. The truck engines better be more of an upgrade as the LS is falling behind and a slight improvement won't get them back in the game. Sounds really negative but it's not necessarily that the LT isn't going to be a great engine, more of a testamate to how awesome the LS is/was and the improvement it was over the Gen I and II.
