[1979 Eldorado]

If you're referring to the 5.0L used in many Broughams until sometime around the early 1990's it was an Oldsmobile 307. The 5.7L which was available around 1991 was a Chevrolet engine. The 5.7L used in the 1976-1979 Seville and the 1979 Eldorado was Oldsmobile based. There was also a 5.7L diesel.

Several variations of the 4.1L as well.

With all three you mentioned there are more differences than similarities so you may want to state the nature of your question. The only thing they really have in common is they were all engines used in Cadillacs at some point in time.
