You've about got it covered. Assuming the 308 you are getting is complete and has battery leads, alternator brackets etc on it

Exhaust
Radiator
Engine harness
Throttle linkage if HQ
Probably kickdown cable setup for 4L60 box on top of engine
Fuel, radiator and heater hoses. Probably a few other hoses too.
Flex plate.
Fan shroud.

Engine mounts are the same, just the adapters are different.
Make sure it has a TH crank in it too, just recently found out TH pattern 308's have a different machining in the rear of the crank for the torque converter.
