I asked Marc H this question. He said a teaspoon amount
is normal. Maybe he was joking, but he said finding no oil
would be a problem.

I found this and hope posting this response is OK with Marc:

"A cc or two of oil pooled in the air duct and a wet air horn are normal for the LT5. Some engines have less of it than your engine, you are on the high end of the normal range. There is more oil when the engine is run hard. That's good for you and the engine. I feel sorry for guys with dry air ducts."

My guess is the last statement does not include those with oil catch cans.
