Definently wasn't the 5.3L. I heard him before i saw him. pulled out from a stop light before we got on the highway and there's no mistaking the sound of an LS vs 5.3L. I would've pulled a 5.3 no problem . . even top end.
And yeah. . dude was pretty old, suprised he took the bait
Yeah, because a 5.3L is SO not an LS. Not to be a penis, but an LS2 in that Fugly contraption should have slapped you around mercilessly at that speed, even with ol' dude's balls trapped under the accelerator.
I may say rude things but learn to take a joke. The internet is funny when you can laugh.
