As far as I know, there is really only one design downdraft intake for the E-series engine. Early [up to '83] don't have the coolant port under the carb, like the '84-'87's do, but other than that, they all look the same to me. All I can imagine you could do, is cut the intake manifold to head flange off of the stock E16 intake, and adapt it to another better intake [like the 2.0L pinto], or build the rest from scratch. It's going to take some skilled work, but it sounds like you have the right man for the job!
