well im searching the market for a new ip, my goals for this truck are like 600-650hp you can see what i already have in my sig im looking for the the best pump for what kind of power im looking for. Im also looking for a bit of advice as well the truck is currently runnuing 4.10's in the rear i cant really punch it in any gear except 5th and 6th otherwise it breaks em right loose im gonna be putting a brand new set of 35's on and i was wondering if you guys had some advice what the best gear ratio would be for the power im pushing i was contemplating either 3.55's or 3.73's i cant get a real straigt answer wich pulls the best and dosnt really fall on its face thanks

 

I liked the 3.55 better than my 4.10 gears. Response was slightly slower, but did not have to shift as often. SO pump will get you to 600-650, but you may need bigger injectors and a bigger clutch.
