I have a full weight 99 Silverado ECSB 4,450lb's its mods are.

6.0 LQ9
Hooker longtubes
3" hooker Y-pipe,single 3" 50 series Flowmaster
Compcam 208/212,554/558,114LSA
eaton posi,4.10 gears
ported T/B
160 thermostat
Tuned by me HP tuners
stock torque converter for now
stock wheels,with M/T drag radials

Im only running 13.7 at 102mph is that about right for this setup,what is slowing me down ? I just ordered a 3200 circle D converter.I do tow my car to the track with this still keep in mind ?? Is my single muffler restrictive ? Is my cam way to small ? Worth swapping out ?

 

Sounds just about right to me. Times will drop with a converter.

 

Small cam and stock converter

I would say those are great times for the mods you have.

also what wheels and tires are you running?

 

thats a little cam

 

For what you have that's not too bad... If your goin with the 3200 converter I would up the cam alittle... You could go with a good bit more cam and still be ok for towing and stuff with the 6.0. You would prolly be good with something around 220 or so. With that and the verter I would think you would be a lot deeper into the 13s

 

bigger cam, stall, and maybe a little head work

your truck is over 800 pounds lighter than mine, have you done any weight reduction?

 

You need a bigger cam.. Once I get my truck back together Ill be pulling my dirt track car to the track with my cam in sig..

 

How did you get the ECSB down to 44oo lbs?

 

99-02's are light. under 4500 is common, some have gotten them to 4000 without too much work

 

my 2000 ECSB weighed 4700 without anything in it. small things like a 2nd battery, 80E, Turbo and stuff.

on my 12.5 pass it weighed 5100 with alot of my crap in there plus a few guns and alot of boolits
