    Ht4100 question

    Is there a difference in the HT4100 engine in a 1985 Fleetwood Coupe full size RWD to a 1985 full size Eldorado. Both with the same VIN code (8). What I wanted to do is use a 4100 engine in an Eldorado to replace my blown 4100 in my Fleetwood coupe.

    As long as their both the rwd engine I would think you'd be fine, but you should post this down in the engine section you'll get more and better responses

    eldorado"s (fwd) use a different oil pan and oil pick up tube...use the rwd parts, oil pan,mounts,and exhaust manifolds and it will work
