What would be a suitable replacement engine for a 1987 Cadillac Coup DeVille v8 4.1L (ht4100)?
Many brands of remanufactured engines are good.
Phone to various parts places like Auto Zone, O’Reillys, Car quest etc to check and compare prices and warranties.
If you’re haveing a shop put it in ask them what brand they prefer.
Are you asking if a different block would fit? Auto recyclers (junkyards) have interchange manuals that list that type of information.
thank-you I’ll research more
