well if u dont know its a 08 rcsb 6.0 h/c full bolt on 6l90 conversion,3600 yank411 so at full weight 20s(4400lbs) and all. 12.80 at 111.5 mph with a 1.82 60ft also it would spin some also it shifting early at 6400 it will be at 7k soon and the tranny hits the limiter 1-2,2-3,3-4 shift.so over all im happy my lowest mph was 107 so if i can switch converter to a 4k cause my 3600 would only breakstall 2500 and light front wheels and the fast intake and tranny tune situated it should do well

 

Nice time for having shifting and traction issues

 

yeah im stoked but now gotta see if any one has a 4k on there 6speed?

 

Nice time; I can't wait to see what you end up getting out of it

 

Congrats, that truck moves! Nice MPH too!!!!

 

Street tires? Lol

 

it was on hoosiers as soon as i got on it it would start pulling hard but then spin into
second

 

What cam? Any head work?

 

Did you flash the converter off idle to see if it ran better? Most do.

 

the cam is from one of my other projects 230/235 600ish lift dont remember all the specs i will find them, the heads r 5.3 2.5 heads 59cc
