1982 Cadillac DeVille Coupe from North America - Comments

I own a 1982 Coupe Deville. I bought the car from a guy that spent over $12,000 restoring it. Needless to say, I paid much much less. I have been concerned about the motor based on what I have read. The car runs and drives perfect so far. It does lack the power of many newer cars, but that is kind of what I like about it. When I drive it, I just kind of fall back into the era of when the car was new. Is it possible if you drive the car easy it will last, or are the 4100's destined to fail?

I have an '82 Deville. Like others said, the engine just dies out of the blue. I took care of mine and it didn't help. I was driving to work and accelerated from a stop light to hear a loud crunching and banging sound. The car then died. After yanking the engine out it ends up the crank shaft snapped... no idea how.

I love my car and that's why I've put an Olds 307 in with 50k miles. To answer the questions, it's not a exact drop in replacement. You have to drill the spots for the Olds engine mounts in the frame and I'm pretty sure the computer won't work either. I put a vacuum advance distributor in and a 70s Quadrajet carb to bypass the computer completely...

I have a 1984 Deville with a 4100 engine! This car can't get out of its own way! Please advise what is the biggest motor with max horsepower that will fit into this car with the least amount of hassle! Willing to replace full drive train if that is what is needed to get the job done,and make this a "Sleeper"!

Thanks all!

To the guy looking for a motor swap... you could go with a carburated 350, or if you wanted to get stupid go with a 472 like in the 70's. I would take some modifying, but it would be cool (no fuel economy though LOL) If it were me though, I'd go with a carb-ed 350 with a turbo 350 transmission. In a coup, that should get er done.

Last year I bought a 82 Cadillac Coupe Deville. It was a 350 diesel, and now it is a gasoline engine. I don't know what engine it is. Could some one help me out. Please.

I may be mistaken, so don't bash me too hard if I am wrong guys and gals, but I believe if you have fuel injection it's a 350 and if it's a carburetor it's a 4100 or a 305 cid. Like I said I could be wrong but I know that's how it is for later years 89-92 sorry if I am wrong,snd i hope this helps.
