if the dpfi manifold bolts up to it then it should work. idk how fine its gonna be because you will lose lots of hp but it should work

your gonna need the stock ecu for dpfi ...cant use obd1 with dpfi need to leave it till you do the mpfi swap... pm5 i think was the dx ecu ..you need to use that with dpfi and distributer and stock harness. i hope it all bults up...
