Hey guys, i've decided to blow my tax return money on a cam, but i'm clueless as to what cam to go with. if any of you could help me out with a part number or some good cam choices for a 2001 silverado 5.3L it would be much appreciated. i'm also wondering if i would need to change the rockers and springs if i got the cam, or would the stock ones work. any help is appreciated, thanks
