mean05 Posted December 23, 2008 Report Share Posted December 23, 2008 LS2 is an aluminum block and the LQ9 is cast iron...im not sure about the compression ratio on the LS2 though i think its a little higher and then you also look at they have different intakes....sure there are a few other differences but i was out late last night so my brain is still asleep Quote Link to comment Share on other sites More sharing options...
