I like that it tells the weight of each engine. It's nice to know that LS motors are lighter than most other engines. Lighter than smaller displacement DOHC V8s so when people say "It doesn't put out a lot of power for being such a big engine." I always said displacement doesn't equal physical size. This'll be a good reference.
And the Carbed LS3 would be a step backwards in technology. Not to mention throttle response and lowend torque.
