i have a 01 chevy w/ 5.3 and wanted to know if i put in a ls6 cam and springs do i need to chang anything else or will everything work fine with this set up and are the springs and cam a direct bolt on with everything else stock???????

 

Yes it should be fine with only the addition of that stuff. If you don't have any other mods...I'd consider "helper" mods first.

Stall
LTs
Tuning
Etc

 

Maybe advance it 4* to bring the power level down a bit.

 

I'm also thinking about an ls6 cam,What would a good spring upgrade be?So it would be ok to run it without a tune until I get all my mods done? Stock or upgraded pushrods? How would you go about advancing the timing?

 

The cam would be ok without tune but you would have to get a tune to take full advantage of the cam. The springs you would need to use atleast the ls6 springs. Pushrods I would use comp hardened rods. As far as advancing it, get an adjustable timing chain from sdpc or more performance. I have a ls6 cam and springs for sale but hitman has dibs on it.

 

Definitely want to go to LS6 springs at a minimum. I don't think the stock LM4 springs will handle the extra lift but maybe this is only for the 02'+ Z06 model cam.
Pushrods are the weakest link in the GenIII engines right now. If you want to live above 6000 rpm go with better pushrods.
