Most likely the fact that your 305E came with the breather in the valve cover rather than the back of the block would make it a 68 unless someone prior capped off the hole in the rear of the block and changed the valve cover. Lets compare engine ID numbers, the 305E that came of my 68 is #305E 497570, get me the number off yours and I'll send it to Lewis to see what year he comes up with.
