I am impressed with the whole general Pertronix story. The innovation, performance, and simplicity in their ignition conversion modules, for example.
When we had my wife's 421 4 bolt main Tripower engine in the 65 GTO rebuilt, and added to the go fast parts and work that had already been done, I decided to get a Pertronix billet aluminum distributor and Ignitor III combo. True multiple spark even at higher RPMs, and a rev limiter, so I could feel better about either of us rowing the gears at the track.
I have a FBO ignition system from Don, a very knowledgeable person who is very adamant about his perspectives on ignition system design and performance. My next ignition system, however, is going to be something that I can tune and tailor to specific needs, and something that I can understand what it is that I am doing.
I haven't even tapped the full potential of the Pertronix in the 421. The kit came with weights, springs, and tabs to control various aspects of the timing curve, and I am going to explore that once we get her 3 Rochester 2bbl carbs modded to accommodate the performance level of the build.
Depending on the results and what is available vs what I want, I may get a Pertronix product for my stroker motor build.
I'm going to check out this Digital HP now.
Thanks.
