You HEAR it's junk. Are you having problems with YOURS? That should be the driving factor. If it is on it's last legs, look for a suitable replacement VEHICLE as swapping in different engines sets you up for all manner of unforeseen problems.

It's the same engine in the Mustangs that year and they are all reliable, Ford worked the bugs out years before.
