Dragonfire electronic ignition 235 ci
Hello,
I have a 47 thriftmaster with a 1962 built 235. I purchased a Dragonfire electronic ignition. My question is what size plugs and wires should I use? Any comments are appreciated |

Re: Dragonfire electronic ignition 235 ci
Any 8mm plug wire will work fine. Im currently using Champion RJ18YC6 with a large gap around 65 I think.

I would not go much over .060" on the gap. Larger gaps can reduce cap life. |

No he was correct with 8 mm. 18 MM is just over 11/16 and that would be pretty fat ignition wires.

Re: Dragonfire electronic ignition 235 ci
I found mine on ebay. $130.00, no wires. Easy to find there.

Re: Dragonfire electronic ignition 235 ci
I put the Dragonfire ignition system with 10.2mm wires. Platinum plugs gapped at .050. Some say you can gap them up to .065.
My mechanic said the bigger the gap retards your timing so I went conservative. Runs like bat out a hell. |

Re: Dragonfire electronic ignition 235 ci
No, resistors are for points to help save the contacts, Most all electronic ignition I know of use 12v. unless its a 6 v system

Re: Dragonfire electronic ignition 235 ci
That is nothing but a GM HEI. Use full battery voltage, no resistor. Gap plugs to .045 - .055.
unfortunately these inexpensive HEI clones have a very bad reputation for reliability. Sometimes the module goes out on the first trip, leaving you stranded. Make sure you have AAA or classic car insurance with free towing. Hagerty is a favorite. |
