There's usually a reason behind why people use similar engine designs...ie an I5 in a truck is a terrible idea. I drove one, drives like the old 4.3, sounds like a 4 banger. GM claims that it has more power than its V6 competitors...to whom are they referring? The Ranger? What happened to Nissan (265hp) or Toyota (245hp)? Sure the 3,5 liter Colorado (220hp) does beat the Ranger (200hp), but that's not much of an accomplishment.
