There's a K1104 in my 'Camino. I bought it as a "temporary" cam until I could decide on something "more". Been "temporary" for about thirty years now. Mind you, this is a 400 with aftermarket heads and Holley carburetion.
Photo from "trial assembly" back in...'91 or '92, maybe.

I'm not saying I recommend the K1103 for a TBI. At least, not unless you've got computer-tuning skills. Maybe it works, I think it's more likely that you'll have problems on the stock tune.
But mostly, I think it's nuts to buy a flat-tappet cam at this point.
Verify that your block does/does not have provisions for an OEM roller cam, and if it does, get all the roller-cam accessories--thrust plate and hardware, dogbones, spider and hardware, roller-cam timing set, used-but-usable roller lifters, and appropriate pushrods, potentially from a Treasure Yard at very low cost--and move into this century.
