2006 silverado 4.8 need more power


Recommended Posts

recently i just did some minor changes to my engine: shorty headers, cold air intake, 3.73 posi rear end, and a EFI Live custom tune. i was looking into porting and polishing my heads and adding a CAM. i was looking into an LS6 cam but i am not sure what you guys would recommend. i want a quicker response from a stop.

no real need to swap out the 4.8. first off i would get rid of the shorty headers and get a set of long tubes. next cam is a great idea but i would do something quite a bit bigger than an ls6 cam. also get a converter.

i have a 99 5.3 cammed out with long tubes and converter. also am currently building an 08 5.3 cammed, turboed, and converter. plus i have a 6.0 i am building into a 408 stroker for an 85 c10.
