After we done the cam swap on my friends 2000 SS we fired it up and it ran perfectly. We did however start it with my dyno tuned computer for my Torquer 2 car while his is in the mail. A few minutes after it started and we reved it a few times (didn't want to drive it) it threw a knock sensor and cam code. He told me it had regular in it so I'm assuming the codes are from the 87 octane. I didn't right down the number for the codes but does that sound logical?
