Lightbulb 1980's Cadillac Replacement Engine

Hello all,
I have a 1982 Cadillac Fleetwood Brougham d'Elegance and I found a factory replacement engine for it with about 20k on it. I know how to identify these engine but I'm wondering what engine is it? I haven't found anything on it really and I'm hoping to hear from some knowledgeable people that know this engine. Is it still an ht4100? How big is it? What does it put out for hp and torque? Maybe someone can even supply a spec sheet so everyone knows about this engine.


Much appreciated

In 1982 other than a limo it should have either a 4.1 liter V6 carbureted engine or a 4100 V8 with throttle body fuel injection. They were used from 1981-85. a different version was used in the front wheel drive 85 and later cars. The 4100 V8 is unique in appearance. The FWD (transverse) and RWD (longitudeal) differ in timing cover, water pump, and intake manifold.

HT4100 252ci V8 very little horsepower and torque. LOL Many parts are discontinued particularly the head bolts.

The 81-92 cars are prime candidates for larger displacement engine swaps. The 86-92 are easier due to lack of computer integration of A /C.86-90 used Oldsmobile 5.0 or 307 the 330,350, and 403 are easy swaps. 91-2 use the 305 and 350 Chevrolet with throttle body fuel injection. The 81-85 can still be done just requires a little more work. There are 81s with the 6.0 Cadillac V8 which is based on the late sixties-seventies engine.
