I have a 2000 Escalade and when you floor it, the car sounds just like it has and LS1 or LT1 it has a Vortech air intake.So tell me what engine does it have and I need a site that sells parts for it! My dad wants to go faster.We drag raced a BMW.

Its a 5.7 vortec v8 its not a lt1 or ls1 ,its close to a lt1 but the water jackets not to mention the heads are completely diffrent .
