I play it the same (with the info that the raise was to 480 of course). You're not quite getting odds to call even if he has KK/AA 100% of the time, felts it post 100% of the time, the SB never foolishly allins, and you don't count set over set. I do think he has KK/AA the vast majority of the time here, but it's only worse for you if he doesn't have it 100%, since you definitely can't 4bet AI against his range and it just means even if the odds were slightly better you still couldn't call for set value.

I don't think limping pre is without its place, but against an unknown at this buyin level I think you'd be missing a lot of value.
