if you have the same year donor, going into the same year truck your swapping to, its a very strait forward swap (plug to plug, bolt to bolt ect.). your tac will more then likely be out, but in the v8 swap tread i did, it shows how to fix that. the only difference will be your ac, and oil sending.
as for a 408, if i am correct, that is based off a 351w block. there are some differences within the bock itself (taller, wider). the cam syc will be difference (302 is shorter so you would have figure out how to make one using different parts) the explorer lower intake will not fit (351w is wider at the top) and the oil pan will not fit (once again, wider, and the main crank cap at both front and back are bigger). lastly, the exhaust manifolds will need to be reworked.
im not saying its impossible, but it will be some work. i would love to see someone jam a 351w into a 2nd gen. i have thought about it, but wouldnt have the patience to figure out all the little problems you would have with it.
i have replaced the 302 with a 347 (it was in another members truck that i bought) and it was instant smiles everytime you'd smash the gas peddle down!
good luck and kept us posted
