Just removed this cam from my truck. Went back to stock to sell it, has about 3k miles on it.
Comp part # 54-451-11. Specs are .554/.558 208/212 115LSA
LS3 blue valve springs, brand new, never used.
Asking $275 shipped for cam and $50 shipped for springs. $300 for both. Will have pics up shortly.

 

is this a cam for boosted engines? do the ls3 springs work with this cam in a 5.3L?

 

Cam sold. Yes the springs will work on a 5.3L

 

Do you know if the springs will work on LQ9 heads? What's the lift spec for them?

 

I'm assuming you just have the springs and not the retainers and locks....right?

 

Yeah, just the springs. Yes, they will work on lq9 heads. According to GMPP, they are good to .570 lift.
