As soon as the warranty runs out I'm gonna throw in a mild aftermarket cam. I really don't want to change out the valve springs if I don't absolutely have to. Does anybody know what lift the factory 5.3 springs are rated at? I'm thinking it's somewhere around .510-.515 but I'm not exactly sure. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

 

.500

 

Is that all? That's the lift of the factory cam in the cars. I thought it'd be a little more than that. oh well, guess I'll be doing springs as well then. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />
