You will notice the rev limit by a large BANG! sound...;>
I believe most MSN ignitions have a programable rev-limiter, so you can change it to what it needs to be. The limit depends on the engine so you should talk to your engine builder. My 351/392 with MSD ignition is set for 5.5k, but I will probably increase this to 6k once the engine is run in and it has been dyno-tuned.
