    you may be over thinking it, cant you just put the plug wires on in a different order to match the firing order of the odd fire? correct me if i'm wrong. - Geoffrey

    No. The odd fire V6 has the same firing order as the even fire V6.

    Not correct. Oddfire and evenfire is the same, 165432. And no, you can't just move the ignition wires. The stators are different and the firing pulses are different due to the different crank design. Lots of discussion on this.

    I have a copy of that on my home computer. I should be able to scrape it up for you once I get home tonight or tomorrow.

    Thanks, I have that site and it gives a good description of the differences but doesn't tell me exactly what I need to do to make the conversion. Or maybe I missed that part. I'll go read it again.


    Warloch,
    That would be great if you could find that.


    Thanks again everyone.

    There is a ton of confusion on the net about this topic. I've seen both conclusions as the absolute truth, and swear this is probably 25% of most people's issues when complaining about not getting their timing right.

    Chuck, I would be interested in a copy of this too. PM'd my e-mail. Thanks in advance.

    Not really confusion, just fact, and non fact. There's really nothing to be confused about, once you understand how it works.

    X2. I don't understand how there is confusion. There's fact and there's fiction.

    This is black and white, it's an odd-fire or it's even-fire. An even-fire distributor can be converted to odd-fire, but not the other way around.

    An odd-fire will run, not properly, but it will run with an even-fire distributor in it. When I got my orange Jeep it had an even fire distributor in it. I drove it like that for a few weeks before I figured out that something was missing...

    I used that distributor for the conversion. It ran much better after that with both cylinder banks firing.

    The page I linked to shows the differences and should not be used as a guide to convert. It is however relatively easy to do and the article Chuck has is very detailed and will walk you through it. This is probably only cost effective if you already have the even fire distributor.

    That is exactly what I was looking for. Thank you very much Warloch.

    And thanks to grannyscj too. Yes, I already have the even fire distrib. I found that out when I was putting the engine back together. Whoever had converted this to HEI before I bought it had put in an even fire distributor. No wonder it never ran right.

    Also, thanks to all the other experts on this site that have given me and so many others great advice in the past.

    Have a good weekend all,

    I just thought of one other thing. Does removing those three lobes on the distributor shaft cause any balance problems with the shaft? I suppose I'll just need to be careful and keep everything as even as possible.

    Thanks again

    I suppose it could but the radius is so small that you have to a major difference in material. Just try to smooth it the same at each lobe and you'll be fine.
