This is a new LS Hot Cam p/n 88958753 pulled from a new, never-fired GMPP LS3/480 p/n 19420384 crate engine. The matching springs and retainers are included, as well as the timing chain and gears from the same crate motor.

I'm also including a new set of 16 Delphi LS7 lifters to make a complete cam upgrade kit less gaskets. Box tag in pictures.

If you are looking you probably know these.. Hot Cam cam specs are:

This is priced right for all that's included, and a great cam upgrade for any LS base cam. 
(FWIW GM used to rate the LS3/480 at just that, 480 hp. Over time they changed the rated output to 505 hp keeping the same name for the crate motor. The Hot Cam proved it performed better in the LS3 than expected!)

I also have the pushrods and oil pump from the same engine for an additional $100 if interested.
