Unless you have an unusual situation, you only remove the hood. Do not start doing bodywork. Removing the fenders still leaves you with the radiator's core support that is welded on, and the inner fenders, so you still have to lift the engine over that. What you need to watch is that the engine hoist will reach high enough for the engine and transmission to clear the core support. Consider using a leveler with the engine hoist. That has four chains, one for each corner of the engine, and a handle to crank the engine forward or rearward relative to the chain on the hoist. That allows you to raise the front up real high to get it over the core support, then, after you pull it forward far enough, you crank the handle to raise the transmission so that will clear too.

Remember the engine with the oil pan is close to three feet tall. The leveler will add another 12 - 20 inches. Knowing that, you can approximate how high the engine hoist will need to reach. If you're short just a few inches, once the engine is supported by the hoist, you can remove the front wheels and tires, then let the truck down. You can also just deflate the tires a little, but I would not allow the lips of the wheels to sit on the tires. Put blocks under the frame to prevent the truck from going that low.

If you are using an overhead chain-type hoist, you still should use the leveler, but you wont have to worry about reaching high enough. You will need to be able to push the truck back though once the engine is high enough. Use a plug at the tail housing of the transmission, otherwise you will dump most of the transmission fluid on the ground.
