Wrong cam??

I have a rebuilt gen IV LS2 and TR6060 into an old shoebox Chevy. The motor is built and I don't really want to tear into it. Has Tick Torquemax stage 2 cam (and ARP bolts, trunion, unported 243 heads). I planned on using the NNBS plastic intake but really want to stay with old-school looking 4150 (no intake on the car yet, I'm doing electrical, fuel plumbing, etc.).

My question...if using a Holley midrise intake (or perhaps Vic Jr), 4150-to-LS3 TB adapter with the existing cam, any ideas on how it'll run? I realize it should use a proper cam for the application, but curious who kind of performance to expect. i.e., will I see a minor hit at the top of the curve or will this be a generally awkward running / stumbling setup vs the intended ugly-*** intake?

Before the flaming begins, yes I know it'll be more prone to heat issues, likely less powerful and less MPG. And that I'm putting 'cool factor' over function (not normally my style). But I've got it stuck in my head...and it'll look much better with the 7-fin Corvette valve covers that are already on there...

This LS intake shoot out article might help give a rough idea. The ugly TBSS is was much better than the Holley mid rise in this test.
