The timing may be off when you changed over to the Pertronix, but it should not be off by 180 deg unless you also changed the spark plug wiring at the same time. I would check the timing while cranking and make sure it is somewhere around 5-10 deg BTDC. Anything close to this and the car should at least fire, if not run especially well. An easy check is to use the timing light to look at the cam sprocket marks when cranking. They should be close to being lined up as shown in the JH manual if the spark is a few degrees BTDC.
