So is it or not a 442 motor?

Wow that is a lot of detail for a 1975 engine.

"So is it or not a 442 motor?"

If it came from that car shown, probably.
However, it is of the EGR era and so "a 442 engine" is really nothing vastly superior to any other similar 350. No magic heads or cam. It's just a 350 4-bbl smogger.

To expand on Chris' response, starting with the 1972 model year, the "442" was demoted to an "appearance and handling package", available with any engine and trans offered in the Cutlass line. Your L34 engine is the same 350 4bbl installed in hundreds of thousands of other Oldsmobiles. There was no unique "442" engine offered in 1975. The 442 wouldn't get a unique engine again until the 1980 model year, when it became the only A-body Olds offered with a 350.

And yes, the 1979 H/O, which also got this engine, wasn't a 442.
