Since this was a factory option, it's a bolt-in. The thing that throws most people is the motor mounts. You can either use the existing 350 rubber motor mounts with the existing metal frame mounts or you can change everything to the correct 455 motor mounts with matching frame mounts. Just DO NOT mix 455 motor mounts with 350 frame mounts - that's where the problem occurs. The only real difference between the 350 mount setup and the 455 mount setup is the 455 parts are beefier (which is why the different frame mounts are needed) but either style, used as a matched set, will position the motor correctly.
All the accessory brackets of that vintage are designed to fit both big and small blocks, usually through the use of two different sets of holes where necessary. You'll need big block exhaust manifolds or headers and you'll want a high torque starter, but everything else is the same.
