if your '85 is the same as my '86, it has a cable from the trans to the
speedo, and a VSS transducer in the dash for the computer.  AFAIK that's
compatible with the trans mounted sensor, because that's what I used for
VSS when I put the TBI 350 into my S-10.  

Unfortunately I don't know what ECM came with the motor, I neglected to
look at it before I put it in the dash.  Maybe someone here knows?  The
motor is a TBI 350 from a '91 Caprice police car.  Any guess what ECM
runs it?
