2012 GrandSport Cam
I'm looking for a cam for my car and am curious to the stock tolerances of the valvetrain. At what point do I need to buy a cam kit that includes springs and pushrods?

I'm far from an expert, but GM sells a version of the LS3 with their "hot cam" that uses the stock springs and such. Every engine builder that specs something bigger normally recommends upgrading the springs.

Yes, definetely the best thing to do too. The LS3 cam has some pretty aggressive specs for a stock cam anyway, i.e. .550 lift, cannot remember the rest, best to do a custom cam.
