Those are some awesome times. 13.5 is about what the bar is set at for a stock engine. My goal is to try to beat that this spring. Here are the pile off parts i'll throw at my car: Slicks/skinnies, T5 conversion, keep the 4.10s i put in, BBk longtubes, O/R h pipe, Already have a bbk CAI on it, subframe connectors (so i don't twist up the body), A shortbelt, up timing, And finally cheat with a little weight reduction.
