3.5 I5 vs 3.7 I5?
I'm currently shopping around for a new(er) truck, and the Colorado\Canyon is on top of my list
anyways the 06/07 models are in my price range, and I'm wondering if there's much difference in the two engines. Power wise the difference seems negligible between the two motors ( yes i know there's 22hp more in the 3.7)

Well this is an old thread, but no one answered so I will. The 3.5 had head problems that they fixed with the 3.7. A great many people even needed to get a new head on their 3.5. I don't remember exactly what the problem is, but if you can afford to get a 3.7 you might as well. I do believe that GM will pay for the new head if you have the problem on the 3.5.
