Let me start off by saying im kind of a newb to performance, and want your honest opinions. I would also like to see what you think my truck should run in the 1/4 mile. i will post what i had in my truck before when i ran in at no problem raceway in donaldsonville, LA to now.

Before

4.8L iron block with 6L cam
tune
vette servo
envoy converter
stock intake
pacestter long tubes/ory
456s w/g80
truck was stock ride height, on stock 17s
ran a 15.5 personal best

Now
5.3L iron block with LS6 2002 Z0 cam, 204/218 Duration @ 0.050
ls6 valve springs
k&n cai
ls1 efans
asp underdrive pullies
vette servo
envoy converter
pacesetter long tubes/ory
456s w/ g80

I have a Hayden Trans Saver 26000 gvw (biggest they make) im about to install.

truck sits at 3/6 on ltz 20s with a 275/45/20

what do you think my truck should run now with this little updates and the bigger motor, im thinking low 14s, possible 13s, im not sure. I will be going soon i hope to see, and will be on 20s. Also, when I get the money together I would like to put in a 3200 stall and a tsp or tr220 cam with hardened pushrods and valve springs, what kind of gains am i looking at compared to what I have now?? thanks for your time.

 

Id say 14.5-15.0...

 

Take it to the track! No one here knows! Why have us guess? Going to the track for the first time can be intimidating I know, but you will get the hang of it real quick.
Here are a few good tips:
1. If your on radials DON'T TRY TO DO A JOHN FORCE BURNOUT! Drive around the water box and try to keep your tires as dry as possible...
2. Make sure you line up your "FRONT" wheels with the staging beams (not your back ones) classic new guy to the track mistake but you will be the *** of the tower guys jokes all night if you do this.
3. Try to line up against ricers it will boost your confidence, and **** them off!

I lined up on a civic SI one time that the kid thought was fast (his buddies wanted him to smoke a truck), after I waxed him he never even came back around. Just made a right turn and went right back to town LOL...

 

What he said ^^

With 20's you will run mid 15's.....but really get to the track and report back!

 

John Force burnout! hahahaha!

Before I get my tune I wanna go to the track. I am too lazy and poor to get a dyno done. Im sure I can find a Geo Prizm out there that I can line up with.

 

Low 15s.

 

well, like i said a ran a 15.5 with a 4.8, but ill be going to the track soon, and will post up what i ran, just wanted to get some thoughts and opinions

 

With my 4.8, I went 15.1 on 20s with full weight, tailgate, everything at No problem. Dropped some weight and put on 16s and went a best of 14.4 at State Capitol, but it runs a consistent 14.6 most of the time spinning a little. However, I think this 4.8 is starting to lose power(150,000 hard miles). Time for a 5.3.

 

well, ill have to update the thread when i plan to go back and see what it runs,
