I found a 5.0 out of a 97 mercury mountaineer the question is could I use this in my 89 mustang or not. It doesn’t have a distributor but coil pack so I didn’t know if it would convert over to a distributor or if I would be fubar buying it. I was the plan was to put an E303 cam in it and go but seeing that it didn’t have a distributor I’m unsure were to go now. It is complete with harness if that matters.
