So got an 85 with good frame, body, etc, but engine burning oil something fierce. Found a good deal on a recently rebuilt 1990 engine in great running order. Anyone from western Canada will know the rebuilders: Hilltop Cruisers. Anyways from the research I have done I will need to use the 85 ecu then switch out all the sensors and injectors to what the 85 used, correct? Would it be easier to just use the whole 85 intake manifold system instead of just the injectors? Finally, is there any difference in the actual engines between the manual and the auto and anything that would need to be changed? Thanks in advance for any and all welcome information.

 

The later engine will have the slightly better intake and throttle body, so best to keep those parts. There may be a few sensor differences between the manual and A/T engine, likely an extra temperature sender or two.
