My experience: LS1 intake - everything stock - 28lb injectors, stock heads, cam, etc - thru cutom duals, 100 shot on TNT wet system = best of 11.67 at 114mph
LS6 intake - nothing else changed - 11.38 at 124+mph
I recently order the R-X intank fuel pump and 30lb injectors. Will be attempting 150 shot.
IMO the LS6 intake and 30lb injectors would help you tremendously.
It would be cool for a 10 second pass (since I intend on doing it for the first time at an import/EFI racing)
