Hi PT,
I picked it up this cam recently not knowing what the specs were and after a little searching I found out that it was a Lunati cam and the part number stamped on the cam was at some point revised. I cross referenced Lunati's site and found the specs listed here:
Product Description
Hydraulic Roller Cam.Good high performance cam with lots of mid range torque and top end HP. Fair idle.
Advertised Duration (Int/Exh): 282/287
Duration @ .050 (Int/Exh): 218/221
Gross Valve Lift (Int/Exh): .526/.534
LSA/ICL: 116/112
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 2000-5000
Includes: Cam Only
Part Number: 20540503
Previous Part Number: 55003LUN
The cam is smaller than I'd like, so I'm going to let it go as it may work better for someone else's project. I bet with these specs it would make a very good boosted cam for a 5.3. Great thing with this cam too is that with the lower lift numbers it will work LS6/LS2 valve springs which are good to .570 lift. I recently got my car back together and don't want to go through the trouble of swapping a cam at the moment.
The cam has a different wear pattern than I've seen before, but nothing catches my finger nail so it should be fine.

Let me know if you have any questions. I'd like to get $225 shipped for it to the lower 48 states.
Thanks,
Ryan
