Hello guys I own a 4.8 2002 sierra and I planing in entering it in the drag in a couple of months.I'm hopping to get it to 9-10 seconds.
Current Mods:Summit Racing air intake kit.
Dual custom exhaust system with a flowmaster cat.
Custom long tube headers.
Transgo shift kit for 4L60E.part # 26-4L60E-HD2 .
Corvette servos.
Custom Basic tune.
I'm planing to change the engine into an 5.7 LS1 soon.
Any other suggestion would be much appreciated.
Thank you
are you talking 1/8th mile or 1/4??
Swap to 408 with big front mount end thread............:chevy:
I really hope you mean 1/8 mile. My truck runs low 10's in the eighth and I'm trying for 9's. It's stock except for the exhaust and tune (which could use work, I'm still learning), but it's got a man pedal so I can launch it pretty hard. Oh ya it's a 4.3 with 3.23 gears.
I sure hope he is talking bout 1/8th.
Our Track is 1/4
come on be nice I'm just learning,why is 1/4 bad,we only have one track in the country dude.
Nothing wrong with 1/4 at all, but expecting to run 9s or 10's with a bolt on 4.8 is, well, rediculous. You'll do 15's at best. I'm not going to start into ways to get you in the 10's in detail but, 700+ horsepower, the drivetrain to handle it and a very well setup suspension. And it all has to work together perfectly. These are heavy brick shaped trucks, not C6's
Well I saw the same truck as mine in the drag it brought 9 man but the engine has been swapped with a 6.2 ,he couldn't have done it without Nitrous Oxide right?
okay... swap yours to a 6.2.... install a 300 shot and a 4l80e. 4 link and 9" rear with 21.5 wide slicks.... and you might wanna wear a helmet...
My truck went 17.0, and it's a bone stock L33. I hope your quarter mile is straight down...off a cliff. That's prolly the only way your truck is gonna go 9s the way it sits. :lol:
The same truck on the outside and the same truck on the inside are two totally different things. People on here aren't being mean, just realistic. If you've seen someone else with the "same" truck as yours go 9's, I would be asking him what he did.Quote:

Look, you want to run 10's. Get a hold of Allen at Nelson performance and Jon at DB Rods, between the two of them you'll get your 10's.
you want to get your truck in the 9-10s in a couple months? sorry but its not going to happen there guys on here that have busted their a$$ to get a ten along the years. it takes time and lots of fine tuning. you better have steep pockets for what your wanting.
do some research on the trucks like yours that run 9s or 10s then go from there
its not nearly as easy as you think it is
,I'm in the mid east bro,but I will try to look em up online.Quote:

If money is not an issue, which apparently it isn't, why put that kit on a 5.7? Why not a 6.2, or heck, an LS7?
LSX454 bacardi and cola...DO IT!!!Quote:

You kinda right,man it will take to much time and money.In the end the car will be useless.I will probably invest in a Zo6,plus it will be a great weekend car ;).
Thnx for your advice brother.
Cool, I think you will be much happier that way. Just watch some of the Corvette videos on you tube. Dear sweet Jesus there are some badass toys.
