Engine, gas, 8 cylinder, 5.3L, sequential fuel injection, aluminum, high output, GM

disputed: the 2009 Colorado lists print LH8 as 5 cylinder, 3.7L, multiport fuel injection, L4, aluminum, variable valve timing, DOHC, which is LLR's wording (the same lists also carry LLR); Wikipedia says the 2009 Colorado and GMC Canyon added a 5.3L LH8 V8, and GM's 2008 and 2009 Hummer H3 lists read LH8 as 8 cylinder, 5.3L, sequential fuel injection, aluminum, high output; the sources here do not settle which engine the Colorado had.
