    Thumbs up 5.3 Colorado

    Hey guys I just ordered a 2009 Colorado with the 5.3 300 HP V-8. I know this is a LS1 derived motor. Anybody have an info/specs on this? Do they call it a LS1 in the Colorado or something else?

    lm7 is the rpo for that engine. it is a smaller cube wise(325cu i heard) but the design is near identical and maybe has more room to work on in a truck but then again it is a colorado.
