I have a 03 silverado 1500HD quadrasteer 4x4 and I am looking to replace the somewhat sluggish 6.0l engine Just trying to find out what size engine I can get and If there are any superchargers out there for the 6.0l engine. It has a 6" lift with 35s I am just looking to give it a little more edge

 

Unless that motor has a bad piston or cracked block, I wouldnt replace it. Maybe it just needs a little TLC. And then some steroids!!

 

no its a good solid motor has about 115 on it... just looking to give it more ummpf or get something that has plenty

 

Cool. A good intake and exhaust would be a start. Then a tune. Later you could get a step up cam. The 6.0 has great potential for some easy bolt on horespower.

 

already has k&n intake and dual exhaust. do u know if there is either a turbo or supercharger for the 6.0 it is 4x4

 

Yeah they make em for the SS's. How much power u want?? Cuz with that motor you could put a hot cam, long tube headers, and a 3200 converter and push round 440 horses easy.

 

what would u recommend for cam and headers and best converter out there... after I get this done would I need to beef up the gears or anything. also looking to do a rear brake conversion but having a hard time finding info on it

 

Im gonna put a Trailblazer stall in mine. Headers is really personal choice so dont matter. There are several choices in cams. Some of the guys with LS1 motors are goin to a Liginfelter cam. Here is a sample video of a guy who has all this but he is also running NOS 125 shot...
