In order of "best" to "worst" the LSx series would look like this (in terms of most HP to LEAST HP, excluding the truck variants):

LS9, LSA, LS7, LS3, LS6, LS2, LS1

The LS1 was the "new gen" 350 at only 346ci and since the LS3 is the "baseline" LS motor for every GM performance car, that would make the LS3 the new "350 of today". It's not directly comparable unfortunately but that's how it is.
Forgot the LS4 not to be mistaken for the 454 but the 5.3L LS4
