what kind power? what kind of times?



'03 ecsb
3.73 g80
6.0 lq4
comp 212 / 218 .522 / .529 114 LSA
asm headers
yank 2600
decent tune
100 shot n20

 

high 12's. no tranny 400+rwhp

just a guess

 

cool, all i really want is mid to low 13's

 

on that motor set up alone high-mid 13s. W/100 shot, high-mid 12s.

Should be worth @310 rwhp N/A, and @400 rwhp w/100 shot.

 

I am going to have near the exact same setup as what you just spoke about.
We've already got out the original motor and tranny and have a lot of the work done....just waiting for the converter and cam before we drop in the new LQ4 6.0 & 4L80E.

My new setup will be as in my signature.
-'01 6.0 LQ4 w/ aluminum heads
-220-224 or something Comp Cam with 560 lift LSA115
-Comp springs, rods, titanium retainers
-4L80E with Transgo Shift Kit
-Yank 2600HD Stall
-3.73 with Eaton Posi & good set of Kumhos
-TOG Headers
-K&N Cold Air Intake
-Hooker True Duals
-43lb. AS&M Injectors
-160 Stat
-LS1 E-Fans
-MSD Wires
-TR6-IX Iridium Plugs
-150 Dry Shot N2O
-NELSON PERFORMANCE Tune

I have no idea what I'm goona hit...I will be happy with low 13s.
My truck is heavy, especially with all the junk that stays in the back seat + subs, etc.

Instead of 4x4 for traction, I just have a bunch of junk in the bed/backseat to keep the tires glued down

 

Might do better power than that.

BLK6.0HD did 337/342 or something near that with similar mods but bigger cam and no tuning. With injectors and tuning he has to be near 350rwhp N/A.

I did 304rwhp before tuning and I have gained 1mph since I a think i am near 315 or so.

It'll be a potent combo that's for sure

 

If you dont mind me asking, what did the motor and tranny run you roughly??
Are you doing the work yourself or having it done

 

I am doing the work.
Motor and trans cost $2500 to my door with 6 months parts & labor warranty (which I hope I won't need, but good assurance). I got them as a combo from car-parts.com
motor included everything from complete intake to pan.

 

Only drawback I keep hearing about is the 4L80's consumption of horsepower. I heard it takes 35hp just to make it turn the driveshaft.

I also hope the gearing in it works for me in the quarter....we shall see!

With the 150 shot (130 went to rear wheels on the 5.3 per dyno--Allen Nelson can vouch--was very pleased!), maybe I'll be close to 475rwhp? Incredible....hope the stock 4L80 w/ transgo can hold it.

I am pessimistic though, I am guessing 450rwhp ABSOLUTE MAX with Nitrous.

 

If I remember correctly. With my stock headed 6.0 at 9.4:1 compression with that cam, it put down 345rwhp and 350rwtq. That was with a stock tune, just raising the shift points at this time. Plus 4.10 gears and spinning some heavy *** 20in wheels.
The 4L80 will hold.
