2003 Silverado SS with these mods

224/227 .563/.569 114 LSA Thunderacing Nitrous Cam
Longtube headers with 3in exhaust
good tune
200 wet shot

A friend is planning on building his SS, and he has this list as of right now. I suggested getting a good stall as well, but does the rest sound like maybe a mid-low 12, maybe even an 11 on a good day?

 

If that's it on the list it won't touch 11s. Does he plan on building the bottom end? A 200 wet shot will not last long on that LQ9 especially with stock injectors and fuel pump!

So I guess with that said, we'd need a final listing of all mods to make the most accurate estimation.

 

you will most definitely need a stall with that cam.

 

There is no way that stock fuel system could support that...

 

255lph in tank, 28.8 LS6 injectors (or 36's, I'm suggesting 36's to him), I did suggest a stall to him, what's a good stall on these motors. I know LS1's love 3000 ranges, I was thinking 2800, what do you think? And from my understanding the 6.0 bottom end is not much different than an LS1 bottom end, with that said, 200 shots last a long time tuned right. Says later on he'll do a 408 when the motor gives way lol.
