4.8 Power?

[buckschatz]

so ive got an 08 chevy w/ a 4.8l v8 that ive been messin with since i got it and so far ive added a k&n cod intake, edelbrock shorty headers a bully dog programmer... basically short of throwing on a supercharger what can i do to put some more power in my truck and whats the best gear ratio to be running (performance wise) on 34 inch tires...

Nothing short of 4.56's in my opinion. The 4.8 lacks the torque of the 5.3 and the little extra with the 4.56's would give the 4.8 the edge. Also a little higher stall converter would do wonders.

kk cool already changed the gears and saw some big changes... and a stall converter? how would i match that up to my engine? and how easy is that to install?

A cam and a stall will really get you some good power. I'd say at least a 3200 stall.

a cam will surely help. you should have saved you money on the short tube and bought LT headers. short tube don't help. once all of your mods are done, buy a custom tune. best bang for the buck and it will wrap everything together.

I have a 09 and have been looking for long tube headers and cant find any. Can you point me in the right direction?
