I have a 4.8 Silverado and what I want to have done to it when I'm finished is a header back exhaust system, intake, tb spacer, diablo programmer and a GM hot cam.

I am wondering if anybody out there has these or similar mods and had their truck on a dyno. About what horsepower/torque can I expect out of this if it is tuned properly?

Thanks

 

Not sure bout numbers, but here is a 4.8 set up with the goodies....

 

wow that sounds awesome! where did you find the video?

 

Just check out youtube.com and search whatever motor or truck you are lookin for.
