Not long ago, I over-rev'd my engine. Luckily, no damage, or at least not that I can tell. I see a lot of mention in this site on rev-limiters. I take it a lot of them work in conjunction with a computer igntion system like MSD.
I originally had a dual points system, but have converted to a Pertronix module. Either way, it appears I need a "stand alone" limiter.
I found this one, the Pertronix 600
Seems to me that cutting ignition (even randomly to various cylinders) and then lighting it back up is asking for trouble with an engine loaded at high rpms.
What can I expect to happen when the rev-limiter comes on (other than not revving higher)? Is it sort of smooth, or does it sound like the engine is very unhappy.....like a lot of nasty misfires, etc.
