It won't be emissions legal, PERIOD. There was never a 455 Olds certified to 1991 or 1992 standards. This swap is unfortunately illegal under federal law and also under any state law that requires emissions testing. The general rule of thumb is that you can swap the same year or NEWER motor into a car so long as you also swap all the emissions equipment required to maintain the emissions certification. This swap can only be registered in states that do not have testing (or with the help of some greased palms).
There are a couple of ways to do this swap. As Stick correctly noted, the 307 frame mounts from a B-body allow the 455 to be bolted in using conventional Olds motor mounts. The other option (which is even easier) is to use the 307 block mounts from a 1980-1990 D-body (Caddy Fleetwood). These mounts are like the 403 Trans Am mounts in that they are metal block brackets that mate to the Chevy clamshell style frame mounts.
