One of the pleasant surprises when working on The Horsepower Monster's 427 Stroker Engine project (if you haven't seen it, check it out here) was the built-in rev limiter on the PerTronix Flame-Thrower distributor we used.
The PertTronix unit is a really nice piece because it puts out a nice strong spark, the mechanical advance system is easily tuned for both maximum and rate of advance, and is really well made. But that's the obvious stuff. What we also came to appreciate during the built is the ingenious rev limiter the engineers at PerTronix have baked right into the Ignitor III module for the distributor. Adjusting the rev limiter is pretty easy and requires no extra equipment.
But seeing is believing, so we thought we show you the process here.
