so yea i just grew from a reg to a ext cab so i was just wanting to know if i can still make it go. haha. what are some of the time you have for your ext cabs. looking at going turbo at 35000 miles you know one of those sts 's haha so times with sts's will help but sc will help too. thanks

 

my ex cab is slow but i think there is a guy on here that has a sts and went low 12's with it on his ex cab. what ever works on the single cab trucks works for the longer trucks as well.

 

I think you could do a STS kit then do a small shot on top of that if you could get enough timing out of it.... I would think that'd be good for some 11.9X's if you could get it hooked...
mine's still slower than christmas but its getting a little better... I just got the stall, rear, and tranny done...

 

read my sig..my truck will move..its beet a 4.8 with a 100 shot and cam..87 gmc with a turbo running 12lbs boost..ls1 camaro's all these with out nitrous..havent ran it with nitrous yet..the 4.8 with a 100 shot and cam has beet a crew cab sts turbo truck. and single cab 5.3 magnacharged truck also..

 

any one else got any input this is alot of help. thanks guys

 

My mods are in my sig and next time I go to the track, I'm looking for some 14's...

 

My mods are in my sig, and Im 4wd. I run mid 14's now.

 

What engine? How much are you willing to spend/sacrifice. Speed costs.
How fast do you want to go...will that be enough when you get there? Don't worry, I can't answer either.

 

haha..15.4 i bet..

 

13.9 for me
