    with the plugs as fouled as you say they are you might need to swap in a new set of plugs as some may not be firing anymore especially if they are NGK

    Accel specs 137 plug for a '70 440    .035  gap , if you have an aftermarket ignition wider can be ok. 
      I'd just clean them up & see if they work then.... I've had to do this several times to mine.

    Bullitt, thanks for the info...are the accels good plugs, should I cgange brands?  Opinions welcomed.....

    Now I remember reading on this site or talking to someone about this timing issue.  They stated that when the #1 piston on compression stroke is TDC the rotor cap in the dist should be pointed at #1 piston.  Is this true?Makes sense!!! just went home on lunch to check out and found the rotor to be pointing solidly at #3 if not in between3and4. Calling MOPAR 911!! Help.....
    I will post pics later when I get home from work

       Always heard that to be true, but would only work on #1.. On your compression stroke it would be about half way, given 20 degrees advance, between the #8 & #1 on the rotor cap...On the exhaust stroke halfway between #6 & #5....

        Now #3 & #4 CYLINDERS are on different sides of the engine...think your confused on something.

    I got tired of tracing them so I made a little cardboard cut out & labeled to place on the distributor while I install  wires

    the rotor needs to point at #1 wire not #1 cylinder ,if it was or is running it has to be lined up pointed at #1 wire ,it doesn't matter where #1 wire is positioned on the dist cap

    Chryco, Bullitt,

    My apologies!!!  I was typing that response using a blackberry while rushing back into work late for meeting not paying attention to what I was saying....Bullitt - your right - confused and in a hurry!!!   So I will try again!!! 

    I position #1 cylinder at TDC then marked the dist housing where #1 and #8 are.  The rotor at TDC is right in the middle of them - 1 and 8.  Is this ok or should it be directly lined up with 1?   See the pic showing marks for 1 on the right and 8 is to the left. 

    Bullitt, thanks for the diagram that helps!!!

    You guys are awesome and I cant begin to tell you how grateful I am for your help (and putting up with my lack of knowledge...some may even call it ignorance).

    I truly owe you guys!!!

    Looks right on, maybe a little to close to #8, that would confirm my suspicion that your HB is a few degrees off...maybe... I don't like the look of that rotor button lots of carbon & the tip looks burned......   
                See if anyone else thinks so.

    Bullit, Chryco,

    I will replace the rotor cap as I also noticed the build up.  However, I am still curious as to what I should do!!!  Chryco stated that the cap should be pointed directly at #1 with the #1 piston at TDC (it is at TDC confirmed with a dental pick feeling when it reaches top).  Right now as you can see in the pic it is in the middle but favoring #8.

    So do I pull the distributor and re-align it or is there another alternative?

    Thanks

    Of course, when the rotor is pointing directly at wire #1, the plug will fire.  And you want this to occur at some point before TDC but probably not as much as your indicating.

    The way I look at it is, one revolution of the rotor (360°) equals 2 revolutions of the HB (720°).  So each plug position on the distributer is 45° apart (360°/8) and is equal to 90° rotation of the HB.  If you're estimating that the rotor is pointing in the middle of wires #1 and #8 that would be about 22.5° on the rotor, or 45° on the HB.  That seems like a lot of advance to me.  I wonder if the distributer is off by a tooth at the cam.

    Of course, I'm not the expert on these engines like some of the other guys here, so see what they have to say.  It just seems like a lot of advance.

    good point....I had not thought of the doubling effect,,

    that is not an issue only insomuch that there is room to rotate enough for timing adjustment

    Hey guys,

    I checked the gap between the pickup and reluctor the gap is 0.010".  Not sure what to do or try next if anything at all.

    I started the install on my TTi exhaust today only to find out I do not have the right pieces to connect from the X pipe to the header adaptors..... :stomp: :swear: :banghead: :banghead: :banghead:  Its ALWAYS something....dang it!!!

    Anyway I truly appreciate all of your input.  If there is anything else that you can think of please let me know....
