What will it take to run 13's

[RichardLSX]

My truck is a 99 RCSB 1500 with a '00 LQ4 6.0 And 4L80e Swap, it has a 3.42 rearend, CAI and a 87 octane tune. Alright my first question is what will it take to get my truck at least in the high 13's, without spraying or boosting. And about how much will i be looking at spending. Surprisingly the best i got it to run was a 15.00 exact, im guessing its a result of my power robbing 80e and 3.42 combo. Thanks in advance

Who tuned it? 15.0 seems way low for a rcsb with a 6.0 IMO. What was your 60 ft? And do you have a locker or LSD?
I would say that 4.10's and a stall would get you were you wanna be.

It was tuned by Flaco from Strictly Performance. I have a G80 but hardly ever seems to kick in. It runs awesome in the streets even from a stop but at the track it bearly even spins the tires?? 3 out of the 4 times down the strip it took off very sluggish and my first gear goes all the way to 60-70mph till finally second gear chirps in, and the 1 out of the 4 it took off spinning like crazy even when i went into second gear. My autotech proffesor said that it sounds like my 1st gear doesn't kick in all the time, which sounds reasonable, but then again its a 4l80e with its 2.48 1st gear and 3.42 diff

With a stock stall that is common at the track. Post up your track times.
Like 60ft
1/8 time and mph
1/4 time and mph
g80 is a grenade. IMO a stall, locker, and 4.10's and you will be at your goal. Or close to it.

Alright ill post em up when i find my ticket. Im gonna go to bed for now thanks for the help jeff

Yeah that seems low for your setup gears and stall that should put but hust so u know 13's aren't as fun as u think next u will be wanting low 12s haha goodluck

[RichardLSX]

I couldn't find my time slips....what could be causing it to run slow

[Beatdown Z]

I personally think it's just the overall setup you have, that's making it slow. You have the heavy iron headed, lowest power 6.0 with an 87 tune. A stock stall, heavy, power robbing 4l80e and 3.42 rear gears which are prob the worst gear for any n/a drag race application.

Edit: you basically said this in your first post.

Try a 91 or 93 tune. Get some LT's. Swap those 3.42's for some 4.10's. Toss in a 3200 stall. Do a cam swap like a 228/230. That should get you down into the 12's.

[RichardLSX]

Yea you can actually feel the the way I lose power to the tranny. "bangbangskeetskeet" you really think 12's with the mods you mentioned?

And what do you mean by "OSS in a 3200 stall"
