Yes it would be best to mount that cam and keep your mind on technique My aunt has no qualms about speed but i havent had her in the car that fast..... just a couple nitrous runs thru 3rd gear .... and she likes it. That wheel spin is hard to overcome and as Rogue mentioned gonna slow a E.T. down. You want boost? there'* always nitrous. There is no supercharged version of the Pontiac LD8 and without a reflash we cant get, I'm afraid it'* a pipe dream. There are some on 4.6 Caddy'* but to do ours would have to be done at one of four places I know of that are allowed to do and reflash and no Pontiacs have step up with the mucho $$$$$$ they would charge to retrofit if possible...... I almost cant wait for mine to fold up and put the next/gen 4.6L in. But bucks are getting thin and my wallet says it hopes the OEM lasts for awhile.
