Rev limiter

[Dime]

I was out driving last night and was driving her pretty hard and missed second and third back to back. (piss poor driving I know, still getting used to the monster) I got off the gas both times as soon as it was apparent that I didn't have a gear, but I still revved it pretty high (not sure how much). Me being the paranoid person I am worries about causing damage.

-My 91 has a Marc Heibeck chip. Does his chip have a rev limited and if so where is it set?
-Is over revving something not to worry about as long as it's not done often with intent?
-What kind of problems can occur from over revving an LT5? Can problems that are hard to pick up on occur, or she's either good or broken?

Thanks for the help more dumb questions to come
