What ALL do you have in your truck to go 13.90s@97mph? Would like to get some high 13s NA with a stock internals 5.3. Just wondering what you got in it. I went a 14.99@92.xx with the current mods, I am wondering if headers, 3000 stall, pully, and maybe some 3.73s would get me close to 13.90s. Already has all the usual mods.

 

Long tube headers, 3000-3200 stall, pulley, electric fan, cai intake, ls1 edit, dual exhaust. Lotsofn says he ran 13.28 with pretty much the same mods by pulling out the passenger seat and front swaybar. I think he has 3.73s as well. I just swapped out the 3.42s for 3.90s, hopefully I'll get to run it again soon.
