The motors and engine ratings SHOULD be identical between the 2. The wheel horsepower and torque ratings may be different though. The only difference I could think of would be if they used a different intake, which I don't think is the case. All the other internal parts are identical.
the 5.3 same as in the Alpha H3 its a slightly detuned, which is odd considering the rearend is a better gearing then even the silverado (you can get 4.11 in the colorado), and considering the trailblazer SS has a 400hp 6.0 in it and that is the same platform as the colorado I havent been able to figure out what warrants the detuned 5.3, anyone??
