The ONLY Pertronix problems occur when NOT following their very explicit and detailed installation instructions. Let me clear up one other misconception while I'm at it. You do NOT need to replace whatever coil you are using before installing the Pertronix.nobody said:I assume that when you say allison you are talking about what OGTS sells. What they sell is the crane system now. A friend and I did kind of a side by side comparison of these two. He has petronix and I have crane. Petronix uses a hall effect sensor where crane uses an emitor and detector light system at the distributor. Petronix goes straight to the coil and crane has a 3x4 electronic box to control everything. Both were very easy to install and in these two cases have worked flawlessly. I personally like the led for point emulation on the crane. I can pull the distributor and put it back without using a timing light. The petronix can be had for around 50 bucks but from what I have read however most people change the coil too. The crane is around 100 depending on where you buy it. I couldn't tell you about problems people have had but I have seen the petronix debugged on this site a few times. I don't know if this is a reflection on the product or just the number of them out there. The reverse is what I have seen on the crane. I did searches for both here and there is quite a bit on petronix and very little on the crane. I guess it is a personal choice thing and about cost too. JM2CW

I need your help again, can anyone direct me to any previous threads on replacing the old contact point to a petronix on a 1978 manta B. Need to get the part no. and a few question. Would I be needing to anything on the distributor or it just a straight bolt on.
