Are you certain that a full 4.0 swap was done and not just the head and MPI? From what I'm getting (if I'm deciphering right) that number is a 4.2 built on Feb. 6th of 1987.

Something is giving a CPS signal if that engine runs. Look behind the drivers side of the intake manifold there should be wires running to the CPS bolted to the top of the bellhousing. It's just below the firewall and hard to see.
