I bet somebody at Lunati got the 0.050" duration mixed up with the advertised duration when spec'ing out that intake lobe.
Looks that way... I shouldn't have assumed "Lloyd Knows Best", as mistakes can sometimes happen. Just have to see what happens here because I would expect there to be more duration on the exhaust side. I pulled the card out, took a picture of it, back in the box, and box with the rest of the parts in their boxes. Shame shame... should have paid more attention. Guess this is a lesson on assuming.
More than that, do the springs he has work with a .681 lift? I'n not sure that's even a hydraulic roller lobe. That much lift looks more like a solid lifter lobe.

Good news, got with Lloyd, Lunati claimed they produced the right grind, but messed up the paperwork. They sent a correct Cam Card and I measured the cam at work to confirm and it is correct.
Surprised they are not both owned by Holley at this point. Lloyd Elliot must have a deal with Lunati because I only paid a few more dollars to my door than I would have on one of their off the shelf grinds from Summit. Anyway one crisis diverted.
For the update... even to do the general brake upgrades I got stalled. Rotors were on two months back order... still waiting for them to ship. In light of that this project lost steam as I completed a few projects on my L98 IROC. It has gotten some aesthetics addressed under the hood, new silicone intake tube for the Supercharger instead of the black dryer ducting Vortech supplied, and then popped a radiator leak.
The C4 went to Mackinaw City for the Corvette Parade though
So, the Camaro is getting more attention right now, and I am having second thoughts on which direction to go with the Corvette. Do I really want to tear such a nice car apart? Should I sell what I have already acquired and just continue to build the IROC? Always something.
