The 5.3L Colorado is here! What's the difference?

I'm planning on ordering one for stock at work here soon just to test drive it. The extended cab 2wd can be had with 3.73s and weigh's in around 3700-3900lbs. It should fly. They are using the same engine that has been in the Trailblazers so it doesn't have the good heads and cam. Both are easily fixed though. Stock quarter mile times should be into the low 14's stock and low 13's to high 12's with bolt on's including a converter. With the D.O.D. it should get very good milage also. I don't see why the 4.8L isn't in the mix yet, but happy with the 5.3L option. If they made a regular cab with the 5.3L I'd consider it as a replacement for my current ride.

It would be the easy answer to the Dodge Dakota's 4.7L and high output 4.7L V8's. In a full size gas mileage is just a hair better if you keep your foot out of the gas, but in a mini truck like the Colorado, the 4.8L could probably see high 20's if not 30mpg with a spot-on tune. I'd say ditch the inline-5 cylinder and replace all 4x4's and Z71's with the 4.8L and have the 5.3L as a sports option.
