I wanted to share the lack of wear on my cap terminals and rotor from the phased MP distributor in my hot rod. 15,000 miles

The primary benefit of a phased distributor is the car runs wayyyy better

rotor
Most Mopar distributors require phasing and it is simple to check and correct

what is this new snake oil thing u speak of?

Yes,, do tell all

Somewhere I read an article on how to do it yourself, but don't know where it was.

Hey Tom how big of a hole did you drill in the cap and those look like blue streak.

hmmm...interesting stuff!

I used to sell these reluctors that were modified with extra slots so the distributor could be phased. That trick worked really well for me back when I was running factory distributors.

These days I run a Jesel distributor and all I need to phase it is to just loosen up the mounting bolts and rotate it into position.

After finding out that AndyF was sold out of reluctors, I corrected the phasing on mine by filing the locating slot on the distributor cap wider then filling the other side of the slot with JB Weld, thereby rotating the distributor cap on the distributor.

Yeah, it's ghetto, but it works until I can fix it right...however that may be.

Mine wasn't too far out of phase. I'm sure there are limits on how much correction is possible using my method. Eventually, the holddown straps would have nothing to grab on to.

so what exactly is the skinny here?

I missed sumthin

what are we fasing?

the reluctor on the dist?

please skool me,would it be the same on a points dist or elect only

what do you look for when see if its off?

how does it get corrected?

just wondering myself,I allways thought indexing the spark plugs was snake oil till I did it

now if I could only remember what direction the electrode on the plug is "supposed" to face

In the case of an electronic, when one of the "fins" on the reluctor is aligned with the pickup (and hence, the ignition is firing), the rotor should be aligned with a terminal on the distributor cap. If not, spark has to jump from the rotor to the terminal every time the ignition fires.

To test, you take an old distributor cap and drill a big hole in the top between the center terminal and the #1 spark plug terminal so you can see inside. Install this cap on your engine. Take a timing light, connected to #1 and use the strobe effect to see if the rotor is aligned with #1 terminal when #1 spark plug is firing. If so, great, you're done. If not you have a phasing problem.

OOOHHH!!!!

I think I gots it now

this hole in the cap...dont they drill a couple holes around the cap to stop the miss fireing from the ionazation(sp?) build up or something like that?

thats what I was stuck on

your talking drilling a hole and checking alinement of the rotor and term...

after going and looking at the old dist<i guess you cant remove the rub block for the points were the reluctor would be...DOH!!

Good explanation, what do you do to adjust an electronic distributor if needed? If filing is not enough.
