If the 454 is complete with accessories such as exhaust manifolds, a/c, Power Steering, alternator, etc., it should be a pretty straightforward swap. Transfer the motor mounts and distributor from the 350. A new exhaust system will likely be needed.
It's mostly a bolt-in. Bring over the accessory drive with the new engine, along with the exhaust manifolds. Transfer the distributor from the 350. "some assembly required"

If the 350 engine is a carbureted engine and not FUEL INJECTED, Then remove the 327 and install the 350 and hook everything back up and your done. They are the same blocks other then the stroke.
