Where would you go....

with a '05 ECSB Z71 w/ basic mods... Air Raid CAI, Magnaflow, billet servos and Nelson tune. It does have 3.42s which is a terrible power gear. I know it has the 310 hp motor. It seems to almost not have enough power to pull the 285 70 17 Cooper STTs good. I have also been outran by an '06 CCSB with 285s and a Diablo programmer and a CCSB 4wd Hemi w/ some programmer. I just do not see this happening.... but it did. So where do I need to start from here... LTs with ORY... just start with new 3.73s or 4.10s maybe a cam... I don't want to be in the 12s but a low 15 high 14 would be great.... any help is appreciated

4.10s nothing less is my two cents. Maybe bigger. I am running 4.10s on my truck and I love them. I still get good gas mileage. Better than in town then a stock truck. Get those and see if those same races arent a bit different.

since your on 33s i would find some 430s
