2009 5.3l silverado performance

[bmcgowen]

i have a 2009 5.3l silverado and was looking at replacing the cam with an after market comp cam, but am unsure of the size i wish to do so with and was wondering if i could get some help. I want to replace it with having to do as little motor work as possible for example changing the push rods, valve springs etc. And also i was looking at agetting a performance tune before and after to see the difference, thoughts please?

If you change cams you will most likely need new springs and push rods.

Chromoly? i'm just looking for low end torque off the line and a nice mean lope

I'm not sure. I looked into it a couple years ago before I decided to just do a 6.0 swap. I can't remember

i'm on a little budget, it's more saving the money and doing it as my old man will let me. Right now the truck is a daily driver and i'm considering a tune for performance and mpg on highway

thank you for the help

[Chris]

Mine is a DD, I can pull over 18 MPG on the highway with the 6.0 and 3.42's

forgot the exact specs, but there are a couple smaller cams that you wont have to replace pushrods and springs. However, for most you will need chromoly pushrods and the yellow LS6 springs

i was looking at texas speed and noticed they sold complete kits that run around 750 bucks, and was looking at a 220R or a 224R

If i was to purchase the full kit, it would work together without any problems to the rest of the motor, right?

The 220 is a nice cam. I don't known what year you have and how the AFM operates if you have it
