I cant believe we are having a debate about an engine that was designed and engineered for 200mph and another for hauling dirt being being better. The LS7 had better be better! Ecspecially since it came with an 80k + price tag new. Now, if the truck motor evolves into an LS killer, ( huge shoes to fill) the LS worshipers are going to eat ALOT of crow. IMO every engine has advantages and disadvantages, the amazing builders on the site are more interested in a challenge that a specific package brings, more than brand.
