What chevy engine went in this car?

I’m pretty sure that was only in buses and heavy duty trucks. Cadillac had a 500ci in the Eldorado though.

I don’t think anything came factory with a 502. It was an aftermarket engine supplied through GMPP.
The Cadillac had a 500, but that was a LONG time ago, and a totally different engine.

No production car or truck ever came out with the 502 CID. not even the buses or deuce and a half for the military. However, GM did produce the 502 and still does as a crate engine for those who choose to race a big block or add a big block to a restoration or hot rod car.

The 502 is an engine marketed by GMPP for hotrodders and racers. It was never installed in a vehicle from the factory. They did sell many thousands of 402s though which were the same engine family if that is what you mean.

According to wikipedia, with uncited references, the 502 was installed in some fleet vehicles.

It was not installed in a passenger vehicle, that much is sure.

The original production 502 cid 8.2L engine was offered as a fleet option in late 1970s and early 1980s Chevrolet and GMC medium duty trucks. Although it survived as a high performance crate engine, the early 502 cid engine production didn’t last long (about 1977-1984 I think) because of the more popular 454 engine. But then production of the 502 was revived in the early 2000s as the GM L18 Vortec 8100 8.1L engine (aka Tonawanda 502 which was built at the GM Tonawanda engine plant), although it is actually a 496 cid engine. But I think production of that engine has ended as well. As for the original factory production of the 8.2L 502 cid engine option, I can recall doing warranty service work on those which was in Chevrolet Kodiak trucks owned by a Pepsi distributor and Chevrolet C60 trucks owned by a U-Haul rental dealer. I don’t recall a 502 cid engine option offered in any cars but there may have been a fleet option in some cars as well.
