Anything special about a 91 318?

Ok I know that stuff. But something different about the mount ears, and something different about drilled oil passages, things like that is what I thought that I remembered about them. Last year LA, 1st year magnum, something about that year engine having some features of both, that older and newer ones don't have?
Some of the early year magnums had the oil passage drilled for rocker shaft oiling. STill, the cam bearing had to be changed for that.
