Thought on this 78 fj40. Have some reservations given it has diamond plates around the tub and it wish it was patina with original red. That would have been cool. Just wondering thoughts from the group.
yes, I do still think it is an earlier engine, with later valve cover on it.
your engine has the air injection ports in the head, the OP's doesn't
and it doesn't make any sense to me why the alternator would be moved to the driver side of the engine and wired versus leaving it where it was stock.
