I bet you crack high13's.Depending on tire height adding 4.30 or 4.56 gears plus a Yank ss3600 or ss4000 converter would put you in the 12's with good air.I bet the trap speed either way will be more impressive then et.

In for track results! Id say with a good tire 13's are within reach as well

yes everything in the sig. I think the lift is .551 .551. Its like a whole new truck now I love it.. as soon as I left the shop I got a red light with a 6.0 powerstroke.. lets just say as soon as my tires hooked up I completely murdered him =]

taking it to the track next friday!! im gonna be running on some of my friends stock 17's. Im hoping for atleast a 14.5 my truck has never been ran before so im pretty excited to see what it will do.

The short times will make you or break you. If you can get it down to the low 1.8 or even high 1.7 range 13's are definitely there. But if they arent DR's or better on them wheels your borrowing you'll likely blow off but regardless ET is pointless its the MPH that tells the tale

allenp

yeah they arent dr's haha. im gonna have major traction issues.. as it is now I roast the 22's at launch so I cant imagine the 17's. I need to invest in some tires..

First off, great numbers out of a 4.8

Secondly, interesting on the 2nd gear to 3rd gear numbers. If I remember right several years ago I dyno'd 305 rwhp, but in 2nd gear due to driveshaft fears. I always wondered what it equated to in 3rd.

thanks.. I really didnt know what to expect cause I have yet to find a cammed nnbs 4.8 dyno sheet but I think it did pretty good since it was on 22's. we were only expecting about 280 and it sure did shock the hell out of the tuner.
