My homie has has 2 1984 Cadillac Devilles and one has the 4100 engine and the other has a fuel injected 252. We're wondering if anyone knows if this will be a straight swap or how many extra parts will be needed to move the fuel injected 252 to the other 84 that currently has the 4100 engine.

a 4100 is a 252. 4.1L or 252 cubic inches. Both are fuel injected.

in the chiltons guide is says the 4100 is a DFI 368

noooo. 368 is a bigger V8. Google liter to cubic inch calculator and see how many liters 252 cubic inches is
