No. According to the L81 registry, all 1981 Corvettes had an L81 engine. The L82 was also a 350, it just had different specifications.

Yes. Although the L-82 engine was not a Corvette "option" in 1981, I've seen at least one 1981 Corvette with an L-82 motor and that option code was clearly listed on the window sticker. I'm guessing Chevrolet used up the last of its L-82 motors in early production 1981 Corvettes. It did in at least one anyway.
