the red wire should be wired from the ignition switch and the white wire should be wired from the starter relay to provide extra voltage when the engine is cranking.

Have used DURASPARK ignition for nine years and have had no problems with both wires together. However the thing won't turn over 6200RPM no matter what gear or carb that we have tried. If you know of a way to turn up the rev's please let me know.

it may not be the ignition system. i've turned a stock duraspark with the blue or black grommet well over 7000 rpms.

Please post any info that you may have on this subject . My team has struggled with this problem for several years and we only have one theory and that is the dwell time may not be enough. Have quite a bit of experience with GM HEI and do not have any problems with that type of ignition . It is a shame that Ford does not share info. like GM Any suggestions would be greatly appreciated. Also have one other question D o you know if there is a difference between 69-80 model flex plates and newer / up to 82 I know that there was a change from balance of engines . my question is more of is the off- set different? We have destroyed four starters this past year.

Ever try a ford tfi dist? If you set your timing at one specific spot tfi works fine. Only 3 wires needed to hook up too- ign-grnd and coil neg.

article in last months ct showing how to wire a ford dist to use hei type module it is on a 4cyl but should not make a difference, thiswould allow using aftermarket modules to correct high speed probs.

russell, i don't know where you got your information, but....when you are cranking on the engine there is a drain on power because of the starter motor, the white wire, wired from the starter relay, will boost the voltage to the module to the same voltage that the starter is getting, therefore making more voltage available to the module to fire the engine.

i've wired the red and white together to the ignition switch and the car was hard to start. it will fire, but you will have to let off the starter switch to get it to fire. in a stock application, there would be no need to retard the timing to get the car to fire. the advance is built into the distributor so it is already retarded before you begin cranking.

let me know what you find out. like i said, i've wired them together and it would spin over fine, but it wouldn't fire until you let off of the starter....it was like it wasn't getting enough voltage with the starter spinning.
