352 engines were almost as common as 390s. It doesn't have the coolant reservoir attached to the coolant thermostat housing of the manifold and it has an alternator so it's likely 65 or 66. No power brakes or steering so it's a basic model. Likely a 352 unless it's a pickup. An F100 could have either engine. The 360 came out for 1968 & later.
