weekend project update-

i've been running a MSD 6 and a Pertronix Ignitor II for a couple of years now. I ran across the articles on the TFI conversion, and since there's a pick-and-pull nearby, figured I'd give it a shot, just for fun.

So...I removed a MSD 6A ($175), and a Pertronix II ($82). (prices from Jegs.)

I replaced it with a set of points ($5?), and a junkyard TFI module out of a '93 F150 ($25).

I didn't change the coil- its a Pertronix Flamethrower. I also left the plug gap alone.

IT RUNS BETTER.
i couldn't believe it. I was guessing there would be a slight performance hit, which I was willing to take, since I can sell the old setup and use the $$ for other stuff.

It starts much easier, and idles more smoothly. i haven't even dialed the timing in- just to be safe, i backed off the initial by 5 degrees (from 15 down to 10). Went for a test drive- no performance hit.

I'm in shock. Obviously, I have no long-term data to share, but I'll keep a spare module in the glove box, and its easy to change back over to straight points ignition if you have to.

If you've been thinking about this one...try it.

 

Good call on the spare parts. They didn't call those "Trouble Free Ignition" with tongue locked tight in cheek for no reason at all!
