Mustang GT 4.6 into a Marquis
I have a 95 Mercury Grand Marquis 4.6 with a
blown motor I bought a 96 Mustang GT 4.6 engine
and transmission that I was going to put in my 78
Cobra but decided to go old school 351. Can I put
the 4.6 Mustang GT motor in the Marquis? Will it
bolt in straight in or will I have to change the intake,
etc. Will the Marquis ECM control the 4.6 out of the
No. A 1995 model is OBD I. A 1996 model is OBD II. Completely different computer systems. HTH. -Jim
Can I just buy a 96 ECM and will it plug into a 95 wiring harness?
You'll have to change the wiring harness, sensors, etc. OBD II systems are completely different and use additional sensors as well. HTH. -Jim
