So a guy says he has a early thunderbird motor. From alternator location it is a modular motor.. How can I tell if it's a 94&95 motor or a 96&97 one and are they interchangeable. Thanks a bunch for any info.
Obvious = 96-97 uses a plastic intake with the throttle body in the center facing sideways, 94-95 uses an aluminum intake manifold with the throttle body in the rear facing forward. Not so obvious = there arent side bolts in the side of the block for the 5h main cap on 94-95s and 94-95 heads will have a F4 prefix at the start of the part number, 96-97 will have F5.
Even if it's for 200 dollars and I may use it as more of a learning motor. Or rebuild it with more of attention to the small details I have always heard the early the 4.6 the more fragile they are and this one does look like it has a straight throttle intake.
You can get a PI motor from a late model Crown Vic from a self service junkyard for $200 or less. That’ll be just as good of a learning engine and you’ll actually have something worth having if you do use it.
