looks like a 6.9 or 7.3 IDI diesel
Yep, looks alot like the 6.9 IDI sitting in my dad's dumptruck.
IIRC same block.
Only stroke is different.
So without numbers it wouldd bee pure speculation
Same block... different cylinder BOREs! Definitely either the 6.9 or 7.3 NA... being an '87 (if original to the truck), my guess would lean towards 6.9.
Check drivers side valve cover for decal. If missing, your only recourse is to pull a head to check the bore diameter...
