    I got a new MSD box for my car and would like to know at what rpm do I need to set the rev limit. This is for a 3O2 engine.

    It depends on how many RPM's the engine can handle. I always set mine to a little less than the red lining point so the engine doesnt ever red line.

    What year 302 is it and what did it come out of? I can tell you what RPM you should set it too.

    If it's a manual tranny, you can still over-rev it downshifting no matter what it's set at

    Had a 6200 chip in it and it was faulty coming in at 5000.The 7400 on was all i had handy,originally thought it was a ignition problem.Figured 7400 was better than nothing if a blew a shift.

    I'm jealous Derek. I only set mine at 7200.
    And yes I have hit the rev limiter with a c4.:)
