Ignition coil

[biggsteve97]

I have an 87 1/2 ton Silvy with a built TBI 350 and the 4 year old MSD ignition coil failed suddenly the other day. Coupled with the 2 recent failures of MSD ignition module in my old MSD distributor and MSD's poor reputation of recent years I am hesitant about purchasing another one. I borrowed the stock 22 year old coil from my project but will eventually need another one. What I am wondering is does anyone have any experience with the Pertronix Flame Thrower D3002 ignition coils? The reviews seem good with almost no failure rate but I am looking for real world experience. Or any suggestions on ignition coils. The stock one is working but seems weak, prolly due to age more than the stock lower voltage output.

I'm running the Accel with no problems so far. 8 months. Ran NAPA stock replacement for three years with no issues before that, but replaced cap/rotor/coil/wires all at once in April.

I would go to NAPA and get one of their Echlin brand coils, never had a problem with those, good stuff.

I wondered about the Accel as well. Mine would be the ACC-140011 remot coil since I have tbi but it has an increase in its failure rate over the last couple years so i wasnt sure. I am considering a new delco coil since they have a high reliability rate even though their output is only 38k volt instead of 48k volt. Im thinikin the higher voltage would help with overall driveability. Wish i could confirm there is an actual differnece

All you need is enough voltage to fire the mixture. Extra does nothing for you. As long as the cap and rotor are clean and the wires are good and the plugs are good and gapped correctly, no difference.

Your distributor like your engine is a system. Replacing one part won't make much difference unless you upgrade everything and tune everything to work together.

Unless your pushing rpm in excess of 4k constantly the stock system is up to the task. I second the NAPA Echlin parts. They are good and worth every cent.

If you do have a squirrel cage that makes power around 5k(like I currently do) then your better off stabbing a new dizzy in there that is already tuned to run those rpm with components that will allow hotter spark through that rpm. Just make sure you know what cam you have and match the dizzy gear to that cam.

On my 91 Silverado, I went through two MSD coils in a very short period. It appears the coils come from an outside the country source (China, but who's throwing names around)and I just went and purchased the right GM coil and the truck is still running. My 84 GMC has a distributor that was built by the "Carb Shop", they used GM coils and internal parts. It supports my 385 stroker quite well, with no issues.
