Re: 86 LINCOLN 5.0 ???
OK, I am wrong. LSC's never had mass air. Also the Hollander interchange is wrong and so is every parts store that lists a replacement air mass flow meter for 1989-92 Lincoln LSC's.
We seem to be getting way off track here and picking some immaterial nits. But HO or not, the Lincolns in question has CAST pistons, regardless of what Mustangs did or did not have.
The Mark the OP is looking at I think is a viable donor though it has major drawbacks for performance purposes with the heads and pistons. If SWMBO needed a fresh drivetrain for her car I'd use it in a minute. If it were my car, I'd consider it a "builder" but basically as good a roller 5.0 donor as any. Just my thoughts, nothing carved in stone.
.... it wouldn't be the first time reality took theory and conjecture out behind the woodshed and gave them a good thrashing.
