Mechainiac, I know that some caddy engines have rear sump pans and some not. This the only problem, as I see it. Find an engine with a rear sump, or swap the pan in the one you have if it's not rear sump, and drop it right in there. This engine is smaller that a bigblock chevy. And if a BBC fits there, the caddy will also fit. Of course there are those little items that makes our miserable engine swappers life a lot easier, just research before hand the exaust manifold models available, the engine can be set back a li'l more(ain't the distributor up front, just like in a Buick??) check to see if more than one option in the water pump inlet like in small mopars, etc...
