In my experience, the main benefit of the Pertronix is the Hall-effect distributor pickup. Getting rid of points means an end to changing points and adjusting dwell. Pertronix says their system increases the amount of energy going to the coil by twice in the 3,000 to 5,000 rpm range. It makes sense it would do this, owing to more precise triggering and dwell management. However, I always install an MSD ignition box at the same time. I take the time to install it discretely and do good wire management so it doesn't jump out at you visually when you open the hood. In my 66 Charger, we were able to hide the MSD box low and behind the air cleaner. One has to look closely to find it. With the combination of Pertronix pickup and MSD, starts are immediate, even when the car has sat for several months. The carburetor has to be in good tune, of course. Installation instructions for both Pertronix and MSD are easy to follow. I recommend both highly. All my cars get them.
