Nothing wrong the previous recommendations but I will be the first to say don't waste your money. IF your truck is efi with the thick film coil you already have a dependable coil that puts out decent voltage if you have the old duraspark with the round cansiter coil you could get a stock tfi coil or a fordracing coil that puts ot 40,000 volts and use it they don't cost much and are OEM so they have to at least be dependable up to 50,000 miles when the warranty runs out on the vehicle, right. You won't see much in the way of performance increase by changing the coil. Put your money into a igniton box the box with actually change the characteristics of how much and when the igniton fires and it will make a difference if you have the duraspark igniton otherwise if you ahve the tfi just put your money into something else you really aren't gaining much beefing up the tfi system. Just another perspective and my opinion, good luck with whatever you decide, later

I am currently using points so maybe the higher output coil would be useful. I have been looking at the Pertronix Ignitor as well, but each article I read always advises a high powered coil too. I like the electronic fix but maybe most of the actual power gain comes from the new coil. What do you think?

Ignition
From my experience working with ignition systems, I have seen very good results from both Jacobs and MSD. The factory ignition is very compromised and a good aftermarket system, if well selected and installed, will undoubtly bring more power, economy, and lower emissions. I like very much "Jacob's Ultra Coil". I also like very much MSD boxes, coils, and cables. The box should be installed in a cool dry place, and the coil in a well ventilated area. To make sure that the energy reaches the plugs you also need to have a good set of cables. Once the whole system is optimized you will be able to increase the gap of the spark plugs and also indexing to make the burning more effective. Although Platinum plugs last longer, ordinary copper core plugs have better conductivity and produce more power. The reality is that current and not voltage is what makes the mixture burns. So the so call high voltage "HOT COILS" not always will provide good results. Whichever system you decide, have good luck and I sincerely wish you good results.

I agree with the previous poster the high voltage coil won't really change anything. I read another article you posted about having a points type distributor and my first thoght was you should change the distributor. YOu can use the petronix many people are happy with it. Something to think about you could get a duraspark II distributor from the junkyard along with the coil and module probably for the same money as the petronix unit. I bought a duraspark II distributor from an autoparts store for $75 with a core the coil for $20 or so straight out and the module $25 straight out. Obviously you would need a cap and rotor. This is an inexpensive way short of sourcing a junkyard to have an electronic ignition. YOu will be happy with it I think for the money. Just a thought, and it is a very easy unit to retrofit only a couple of wires, something to think about, later
