if I had my guess I would say it says "except 7.4L or 454" Because i think the 1 ton trucks or something carried the old bodystyle also until 91 and utulized a two headlamp setup, so being that only the 1/2 ton burbs and blazers(maybe others, not sure) carried the new quad headlight setup i'm guessing you couldn't get a 89-91 1/2 ton burb or blazer with a 454?(or anything that had the new quadlamp grill setup). basically i think what the exception means is that if your 89-91 truck has a 454 then it is going to use the dual headlight setup, so the quadlamp rad. support won't accept the dual lamp grille setup. but anyway to answer your question about the 91 quadlamp rad. support it will work just fine with your bigblock 88 suburban. for the quadheadlamp design you need a quadlamp rad core support for a 89-91 1/2 ton suburban and it will bolt right up no matter what type or size engine you have, radiator and all, of course you will need all the grill parts and lamps and such. I hope that makes sense, i'm allready confused just reading it back to myself. maybe someone will straighten me out if I'm wrong.
