I consider stall a bolt on... So a 4.8 with all bolt ons including a 3200+ stall should be in the 13's easily.

 

just add a 100 shot and youll get there..nitrous isnt that bad and its a bolt on

 

Sure you can, all you need is a throttle body spacer, they give you like a kazillion hp/tq!

I would recomend a good stall/ gear combo this should be determined by tire height etc.
Also a great tune, dyno or Nelson IMO
longtube headers

And full boltons, every little bit helps, Like e-fans, pulleys etc.

Please note that 13's can be alot $cheaper with the 6.0swap
with that swap and a tune your there!

 

Yes it can....I've seen 5.3's hit from a 13.4 to 13.6 with boltons. No reason why a 4.8 shouldn't dip into the 13's..

 

I think it possible..im going to the track tonight to get some basline #...

 

Stock: 15.81 @ 90mph

I ran a 15.5@90.5 with a Muffler & stock intake modified/ those mods + 125 shot I ran a 14.3 @ 98mph.. Now I have gear, tune, posi, Intake , and throttle body spacer ..

My best time is 15.5 @ 92.1 and that was without gear, posi, and tune..

 

get some 4.10's youll be hittin your self in the head for not gettin them sooner..also get the ''Tordnado'' another of this BIG power mods

 

a N/A (nitrous assisted) 4.8 can easily do it

 

I dont want to put 4.10s in it because i have to drive 50+ miles to school everyday and i need the gas millage.

I went 16.066@86.69 my 60ft was 2.5 (no spinning)

I need a way better 60ft.....

 

What gears do you have? I'm running 3.73's and IMO a 4.8 should have no higher gears than that because of its lack of torque. A good converter and lower gears should definitely help along with a good tune. The mileage difference isn't that bad with the lower gears; best I ever got was a little over 21 mpg. It'd a little less with the 4.10's but worth it in the long run.
