Gracious ... I have a '74 parts car in better shape. Believe me, after a while, you're going to want to "learn" on something else.
It's going to cost WAY too much in time and money to bring that example back up to speed (pardon my pun),
regardless of how much of the work you do yourself. Unless it has a history of some rock-star/actor/president/gangster dying in it, restoring this one will hollow out your pockets, fast.
Perform a hunt for a better (less rusted?) example (maybe a 73-74 2.0L), than cannibalize/merge the best of the two. Either that, or start a neighborhood "Save The 914" movement.
