Sounds good.. WIsh the 3.8s sounded like that.

wow u are retarded, it is an ls4 and it is based off of the truck motor but is a bit smaller to fit FWD cars. the ss impala has an ls4 also, do some research next time before posting false shit

To poster of this video: GM does not and did not make an LS4 as we're are just getting the LS3 ( aka: 2008 vett and 2009 GXP G8). Your car has the same LX series 5.3 litre truck motor that's in the impala SS for same years 2006-2008

sounds sick
