if a v8 is only runing on 7 you will always feel that "miss". my dads truck had a cracked spark plug that drove me and him crazy for a few months. would do exactly as you describe. test: plugs, wires, cap, and coil. and like storm said, a computer will probly tell you which cylinder is misfiring, if it is..
