I'm changing the motor in my 90 BII which according to the date stamped on the old block is 6/87 - 20C. The motor I'm installing has 11/89 - 20F and is out of an 89. I noticed that the plenums are a little different as one is slightly longer than the other in the snout to the the throttle body. I can't remember which plenum was on which motor and wondering if it makes any difference which one I use? The numbers on the plenums are RF-E67E-9425-CB (cast) / P2 04217ML (stamped). The other one is RF-E87E9425-AA (cast) / 06B2289 (stamped). The Bronco has cruise control with an automatic transmission.
The other question is the ECM, I have the one from the 89 and it was a manual transmission. The one in it with the old motor was already is for an automatic transmission. I'm not sure if the ECM was swapped for the 87 and does it make a difference? I'm assuming that the ECM is the original with the 90 motor, but yall know about assumptions, and they usually bite me in the ass.
The original motor was swapped a long time before I got it.
Thanks and I'll probablly have more questions later.
