new best in box stock ext. 5.3L
ran the truck last night at BMP, and was hoping for a 10th or two quicker than the 15.82 @ 85 I ran about 4 months ago. truck is a 04 ECSB SLT 5.3 2wd 9400 miles and box stock. with a 1/2 tank of gas it ran a 15.500 @ 86.68mph 
I was really happy to say the least. not bad for a stock loaded ecsb 5.3
