pertronix,risistor?plug gap?

i have a totally stock 68 f100 360 i just ordered the pertronix part #pnx1281 from summit, the cheaper one, i am using stock coil, do i need to worry about that ballast resistor wire, and i am running plain old autolites gap at 35 do i need to change that. i am looking more for reliability than anything, i dont want to alter wires if i dont have to. can i put this unit directly in regap the plugs and be on my way. thats what i am looking for. thanks for all the help. i have been messing with points, dwell,gap,timming for two days now. thanks for all the info in these treads, for putting me on to the pertronix. i cant wait till it get here.

I put my pertronix on a stock 390 - didn't even know about a ballast wire. New Autolites gapped at spec. New 8.8MM plugwires, big dizzy cap conversion.

Starts like a dream...

It comes with everything, just follow the instructions... it's a bolt in and run it deal. I did mine during a rebuild so I don't know if you will need to play with the timing, but that's an easy task. I would change the wires, cap and plugs to get the most out of your new spark system!

I think that if you really want the full performance gains from the pertronix you need to get the coil that goes with it. I just did this conversion (I used the pertronix 2) in a 72' with a 390. First I put in the eletronic pick up device and It did start and idle a little smother, then I put in the flame thrower coil and realy started to feel the dfference. finnally I re-gaped the plugs to .050" and good golly did that make it RUN. I don't think you can run a gap that wide with the stock coil, so I felt like I didn't get the full performance gains till I did all this.

P.S. you don't need the resistor wire, remove it.
(I also am running 8.5mm SP wires)

First You need to setup the air gap on the new unit just the way you do on the old points. Then set the engine timing 6-10 BTC
