5.3 bolt on times?
 

i got a 04 ecsb 5.3 with cold air intake, e fans, mid length headers with no cats, 4.10's and a tune. what kinda times could i expect? What is everyone else running with just bolt ons? thanks!

Prob high 14's

14.70ish on stock tires. 14.40-14.50 on drags

thats not to bad for a heavy truck. What are you guys running with bolt ons?

I haven't had the chance to take mine to a 1/4 mile track, but my crew cab with cold air, long tubes, no cat y, tune, catback, 3.73's, on 22" wheels ran a 13.02 @ 81 in 1000', should be a low 15 second run. I just added a 2800 Vigilante converter and am fixing to put a 218/224 cam in it and head back when I come home in May.
