Well - define: work good.
Hmmm.. guess I don't recognize the part number, anyhow..
It will physically install into the motor, yes. The lift, even with 1.6:1 rockers isn't enough to have problems with the stock (assuming..) valve springs. So, yes, it will "work".
However. It will Not pass emissions here in taxachusetts, or I'd be real surprised if it did. It will also not run even reasonably well without some serious playing around with the chip (timing tables, IAC positions, probably the MAF tables to get the BLM's back right, etc..). If you are prepared to get a chip burned for it (or to do it yourself) then, by all means..
With that much lobe separation....certainly is "old school".. although I wonder how much lift (and is it Valve lift?) it's measured at?

It should start!! maybe even run!! Im no cam expert BUT isnt the whole design of a solid lift cam for higher RPM to keep lifters from floating or chattering (whatever the technical term is) and usually designed to come in at 2K or more and go to 7 or 8K?
I am prob waaaay off on this BUT this is the assumption that I was always under.
If this is the case wouldnt this be the worse cam you could put in a L98 with the stock TPI setup?

I read somewhere that the TPI cam lobes are indexed to take advantages of the runner air pulses instead of using the same geometry for the regular carb intakes
