I know this subject has popped up time and time again. I'm looking for a list of cars/years/models to look for with the 4.1 in it. I would think that all the late '80s models in the yards have been reincarnated as Expeditions. Thanks.
80-84 Fullsize Buicks
80-84 Fullsize Oldsmobiles
82-83 Buick Regals
80-84 Cadillac Fleetwoods/Devilles
80-84 Buick Riviera, Olds Toronado, Cadillac Eldorado.
Beware with the Caddys. If it says 4100 or HT4100, that is the 4.1 liter aluminum V8.
The easiest way to tell a 4.1 is the 4 barrel Quadrajet carb. Other than that, they look like any other Buick V6.
